Oh, somewhere around 24" across, 15" deep, and 16" tall. 8-)

The first floor section printed fairly well on the SD printer, aside from a really odd discoloring effect from where it was in contact with the glass plate. I'm not sure if it's the filament itself, a chemical reaction to the hairspray, or what. It doesn't really spread more than a mm or two from the bottom, and since it's confined to the underside of the floor panels, nobody will be able to see it, but I certainly hope it doesn't do this when I print the top parts of the console later.

Hopefully, by then, I'll have the HD machine fixed, where I haven't noticed any discoloration issues on any of the previous PLA+ prints I've made.

The discoloration reminds me of my old Star Wars toys that got left out in the sun. I'm pretty sure I had a Chewbacca that was that same sickly color of brown on one side.

Good news: Everything's fitting together beautifully, and the off-the-shelf 22mm acrylic tube I bought on eBay for the Time Rotor looks to be just the right dimensions.

Bad news: My HD printer is still offline awaiting some basic parts, but my SD printer just self-destructed in a pretty major way. I think I made a big mistake going with the Flexion Extruder upgrade, and while the BondTech upgrade I use on the other machine is prone to jamming when it's time to change out the filament, at least it prints reliably the rest of the time.
This is the second time the Flexion has essentially backed up all the way up through the guide tube into the extruder itself, ruining almost every part along the way.
I'm sick and tired of having to replace all these bits and pieces (which are weirdly proprietary to the Flexion extruder, and therefore 2 or 3 times as expensive) so I'm biting the bullet and swapping the whole extruder/heater/guide tube/block with a BondTech similar to what I use on the other machine.
It does mean hacksawing out a new hole for the guide tube, since this particular extruder mounts the opposite way around, but I'm pissed enough that I'm willing to give it a try. Unfortunately, I still have to wait for a replacement heating element and guide tube to come in the mail, so no more printing until at least the parts for the HD machine get here, hopefully over the weekend.

Got the parts to repair the HD machine today and after replacing the heater (which needed replacing anyways since it's had a loose wire I've had wrapped in electrical tape for over a year) and thermistor (which had broken loose from it's metal casing, undoubted causing my "heater errors"), it now seems to be printing fine, though the X motor was making a very odd low level hum when I first started it up, which is strange, since that has absolutely nothing to do with any of the parts I just replaced.

Sigh.... Probably another component waiting to go out.
On one hand, it's nice that most of the standard-issue parts only cost between $8 to $15 and are usually pretty easy to swap out, but I wish they didn't have to be swapped out quite so often.



For those who are interested, the latest generation of resin printers just coming out on the market are finally catching up with filament printers in terms of build area, making them more useful for customization.

It used to be the Moai printer was the biggest resin printer on the market at 130 x 130 x 180 mm, but Wanhao (the company who makes my filament printers) recently released the Duplicator 8 which has a 190 x 120 x 180 mm build area, and there are already competitors popping up like the Tianfour Super King Kong (which I want just for the name) which can do a whopping 200 x 170 x 280 mm (or 7.8" x 6.6" x 11.0")


That's actually a larger total print volume than my HD printer, and big enough to print a full-sized TARDIS or even a Bessie or Whomobile in one go!
The layer resolution is actually slightly less than my HD filament printer (25 microns instead of 20) though the Moai still has them all beat in terms of print quality with an insanely detailed minimum layer height of 5 microns!


Unfortunately, the costs for all three are still pretty steep. The Duplicator 8 will run you about $1100 on sale, while the Maoi costs closer to $1400, or $1700 for the Super King Kong.

Note: The Duplicator 8 is a DLP printer which uses a different voxel based print process, which means up close, it's going to be more pixely and have more distinct layer lines on it's curved surfaces than true SLA printers. But on the plus side, it's supposed to be faster, pretty user friendly, easy to maintain and replace parts on, and can apparently print using almost any UV resin.

Haven't been able to do as much design work lately as I'd like because of all my machine problems, but I did create tiny little functional control levers for the console! They'll be held in place with equally tiny 2mm screw from the underside of the console, and should pivot back and forth in their tracks.

They're slightly fatter than they'd be in true scale, but I'm quite chuffed that they printed at all. At only 2mm thick, I think they're the smallest parts I've ever successfully printed!
Image


It also gives me hope that these tiny little rotating date/time/location components may actually print... at least on my HD machine or in resin.

Haven't updated on here in about 2 weeks (about half of which was spent feeling sick), so here's a rundown of what's been accomplished since then.

Image

All the arches, console feet, and floor plates are completed. I can't really print anything else brown until I completely finish the design work on the console, so I may switch filament back to grey and start printing the top part of the column tomorrow.

Image

I spent an entire day ripping out and altering the mechanism for making the time rotor move up and down. Instead of an entirely internal mechanism, there's now a small lever on the underside of the console that will make the bottom half of the rotor rise and fall. It's small and out of the way enough that most people shouldn't even know it's there, and I think it'll be a lot more reliable in the long run.

Image
The upper part of the console uses a plunger mechanism and a 40mm spring to keep the rotor raised by default. (Otherwise, due to gravity you'd always have the top rotor just hanging there in the lowest position) and both sections have internal guide rails that should keep them perfectly vertically aligned, and limit the travel path to exactly 10mm. The Seal of Rassilon on the top can be used to operate the plunger, but since this adds 30mm to an already massive design, I've also provided a flat "cap" piece that's not quite so tall, which can just be popped on and off to access the light switch and plunger.

Image

As for the console itself, I've been working on making functionally rotating versions of the destination settings.

Smappy's design had these already, with the idea that you could swap the cylinders out of you wanted more than 6 choices. It's a clever idea, but I don't think it's possible, even with a SLA printer, and especially not after I slightly shrunk everything to make it more screen accurate.

The current plan is to have the cylinders slot in and lock in place from the underside when you're assembling the console, though it's still a leap of faith assuming that they'll print at all.

Each cylinder is about 5 to 6mm across, which is pushing the border of what I'd consider the minimal safe size to print. They will probably print file in SLA, but ideally, I want the entire project to work for anybody with a regular filament printer. Even if the cylinders print, I don't know if the lettering will, but I'll include an alternate blank option for anyone who wants to try using stickers.

I'm slightly flubbing the design a bit by merging the gear toggle with the display for all but the very top row (which is oddly disconnected) the thought being that it might make them slightly easier to spin during play without having to resort to a pin or toothpick. I'm also going to cheat and make the month/day and hour/minute/second cylinders all one piece, again, in the hopes that it'll make filament printing easier.

Image
In other news, I should be uploading files for a slightly improved version of the 20th Anniversary Console in another day or so.

The main changes are creating a deeper spring cavity for the time rotor (which should allow for better range of movement and mean you don't have to cut the 40mm spring in half) tracks and guide rails on all 4 sides to keep the central column level when moving up and down (at least in theory), swapping out the dual LED battery pack hole for a single (it's not really necessary, since a single 20 LED light string works just fine, and the lights should be white rather than multi-colored anyways), splitting up both halves of the console to hopefully improve printing and reduce overhangs. And just because, there's now a removable access panel in the base if you want to have the Doctor do some tinkering. I may make some dummy circuit board components to go inside as well.

Amazing. It just keeps getting more elaborate. I'm now officially intimidated to try to make one. :)

Just wait... This guy who recently joined my Facebook group builds and sells custom Lego light kits, including ones for the Lego TARDIS sets.

He's apparently working on a new batch of small light/sound modules, and thinks he can build one with RF controls and a small piston motor!
I've basically told him, if he can build it, I'll find some way to work it into my designs. I'm sure the kit will cost you a small packet, but for really hardcore fans, it may soon be possible to not only have a fancy light-up console, but one that moves on command and plays the dematerialization sound effect too!!!!

023 - Season 14-17 Newbery TARDIS
Status: Untested. May need additional fine tuning.

This started out as a quick favor for a friend that quickly ballooned into a full-fledged figure of its own.

Originally it was just an alternate roof and base for customizing the Character Options Yardley TARDIS (which is pretty close). This proved to be not as good as it could have been, so he sent me a 3D Yardley TARDIS designed by someone else (I've got the parted out pre-tinkering version up here: https://www.tinkercad.com/things/0IoQXJb22md if anyone wants to play with it) which I was just supposed to move the lock and mantle signs on. Well, perfectionist that I am, I went on TARDIS Builders and noticed a whole bunch of other things that would need to be changed if it was going to look accurate, so I more or less rebuilt the thing from scratch and added a secret compartment in the roof where you can hide a Mini Keychain light to make the lamp on top light up at the touch of a button. I may also make an alternate back panel that is easier to pop in and out, just like the actual Newbery TARDIS.

Note: I don't really plan on doing any more TARDISes, especially because they seem to be the one classic series toy that Character Options are actually releasing new versions of. It's entirely possible that we may get a new 4th Doctor set at some point that contains a Newbery TARDIS, at which point, this design will be pulled from release, as I've promised with all my designs.
