TildaCage - Modular Tildagon Case + Diffuser

Cage/case for the EMF Camp Tildagon, designed to make physical interfaces a bit easier for Tildagon projects. Will clear any Hexpansions that follow the standard guidelines (though not the Keebdexpansion, yet…). It also gives a nice diffusion to the LEDs around the sides.

.step files included below for modding this.

The baseplate has mounting holes for accessories, including these: https://www.printables.com/model/1802686-tildagon-mounting-system  . The central hexagonal hole is 48mm across from flat-to-flat.

The other reason the baseplate is so full of holes is that I wanted it to obscure less of Morag's lovely PCB artwork. They also make the Tildagon slightly easier to hold (relevant image shows an earlier prototype, with only the central hole).

To build the case, you'll need six M3x30mm countersunk machine screws, three M3x12mm countersunk machine screws (to replace the three screws that hold the Tildagon together), and six M3 nuts to embed in the baseplate.

The button module is optional, and fits in the same baseplate sockets (4.75mm x 24mm footprint) as the diffusers for the USB ports. If you do install the buttons, be very careful with the middle switch (Boop) of the Tildagon. It sticks out past the edge of the PCB, so pressing it down carelessly into a case could break it off. There are three buttons in the print file; one is shorter than the other two and marked with a dot. This one is specifically to clear the Boop switch; the others will not and might damage your Tildagon if you're careless about that. If you don't want buttons, you could just install the diffuser with the hole in it to leave the switches accessible.

There are two ways you can build this. The first is to fully assemble the case, carefully lower the Tildagon into it then secure with three M3x12mm countersunk screws underneath. If you opt for this route, be very careful not to break your Boop switch off. When inserting the bottom board, it's best to feed the edge with the three switches under the bezel before the other five, to make sure the Boop switch clears it. Once the middle board is past the bezel, you won't be able to see the switch. Do not force the Tildagon down if that edge seems to be snagging on anything!

The second way is safer but more fiddly, and that's to build the case up around the Tildagon:

1. Press six M3 nuts into the holes on the underside of the baseplate (if you're using a mount from the system linked above, insert it now, before securing your Tildagon in place)
2. Remove the three screws that came with your Tildagon from the underside, then mount it on the baseplate using three M3x12mm countersunk screws. They're long enough to reach through the lowest standoffs and hold your Tildagon together with the baseplate.
3. Stretch an elastic band around the sides of the baseplate.
4. Insert the six uprights into their baseplate sockets. The top of each upright is flat, the bottoms have pegs for these sockets. Once they're all in place, gently work the elastic band upward by a centimetre or so to hold them in place against the corners of the Tildagon.
5. Insert any other accessories you want like the button module or USB port diffusers. They should be a snug push fit with the baseplate.
6. Drop the diffuser panels into place. If using Hexpansions, obviously leave those panels out.
7. Place the bezel on top of the uprights. It might be a tight fit around the front board of the Tildagon, but don't worry: the PCB is much tougher than most filaments. The groove in the underside of the bezel should snap into place over the diffusers.
8. Insert and tighten the six M3x30mm machine screws to lock all the cage pieces together. Done!

Kliment: Yes I know the Tildagon doesn't need a case. That's why this one is designed to do more than just be a case, and why every part of is is modular. I'm very impressed by all the clever design work the badge team put into making the 2026 Tildagon more robust than the last. I love this thing, and just wanted to add pretty diffuse light and other ways to mount it. Thank you :)
