DND spells keycap

Description

I designed these flat keycaps with the spell symbols from Dungeons and Dragons on them! They fit cherryMX style stems They are two pieces and require superglue or another type of glue to be assembled. 

Filament

The pictured print is in Bambulab Basic PLA, I don't suggest the purple for the opaque part of the key because it has some light transmission so it doesn't look quite as nice but I am currently out of filament that would work better as of posting this. The purple looks nice with the RGB off though. 

You want to make the stems and symbols from a filament with good light transmission to get the best light effect through your keycap. I used Bambulab PLA basic White as I noticed that the light shines through it pretty well and it is decent at diffusion. A clear filament would also likely look great in these.

Extra points to anyone who uses PET1 to make the light transmission parts!

Nozzle

The Nozzle I have used is .2mm as the details are quite fine. If you decide to use a .4mm nozzle I would use Arachne to try and better fill in the details of the symbols. Please post pictures of your results if you do!

First Layer

The first layer temp that I used was 230c. This is to ensure there are no gaps between lines on the first layer which is the top of the keycap and I recommend doing the same or choosing a temperature that you know will fill in all those little gaps on your first layer.  You'll want to print the first layer nice and slow too, the delicate shapes are prone to peeling off.

 Make sure your bed temperature is high enough to keep them from cooling and peeling off while printing. For PLA, I set my bed to 65c and I have an enclosed printer. You may still need a brim to keep things from peeling up.

Stems

The keycap stems were made for the generic key switches that the macro keypad I have pictured came with, they are cherry mx style. I have included some stem pieces with tighter tolerances in case your switches are different or your printer is not hitting the tolerances.

The stems are marked with notches denoting how tight they are. Print some test stems first before making a whole set!

Notches: 

     None - loose

     One - .1mm tighter

     Two - .2mm tighter

Slicing

The models are multipart STL files, so each keycap has multiple pieces in it that you will need to select the filament color for individually and requires a printer that can handle multicolor printing. In Bambu slicer when you import any of the models you can switch to the object tab and select individual pieces to select your colors. The process in Prusa slicer will require you to import the model and then, right-click it and split it into parts. Afterward, you can change the colors of the individual pieces in the sidebar on the right side after selecting the piece in the viewer. 

I found that getting a print that didn't fail on the first layers required that the images on the keys be printed at the same time as the top of the keycap, which I had placed touching the build plate in the slicer. You can try it with the tops not touching the build plate but you'll need supports and I didn't test that so your results may vary. Please post pictures of any successful prints with supports!
