Sofle Keyboard case (plates) with heat-set inserts and TPU dampening pad

Recently, I built the famous Sofle Keyboard (RGB PCB version in my case). I was trying to find even a simple case. I couldn't find anything that would satisfy my needs, since looks like many people design cases without using heat-set inserts. Maybe because of dimension constrains etc. I like using them, since you can disassemble the device many times if needed. So I had an idea to use inserts, but to glue them since there is no place for additional plastic near PCB holes. Works for me, so I wanted to share it here :) 

I also added some TPU dampening to the bottom plate, since whole keyboard is on a stiffer side and some silicon or rubber feet were needed anyway. I am adding flat bottom and non-heat-set inserts version of plates as well. 

Additional visual detail is that distance from the PCB is equal to top and bottom plates - looks nice.

Electronics cover was inspired by the model from this design:

Besides, you can see on pictures some nice knobs for encoders. Link for those below:

Hardware required:

• printed parts of chosen version (left and right parts + encoder base covers x2)

• 10x M2x8mm screws

• 4x M2x8mm or M2x10mm screws

• 14x M2 (M2xH4xD3.5) heat-set inserts

• few drops of super glue (or other metal-plastic glue, preferably transparent) or epoxy

• toothpick or some small pick to help distribute the glue

• less than a meter of a TPU filament + cutter

• soldering iron (or glue again) for electronics cover inserts

• BONUS: some kind of electrical tape to make the keyboard sound better ("tape mod")

Process of the assembly is quite easy, but do it carefully. Inserts have to be placed perpendicularly to the plate surface. Give a glue some time to cure after applying. You can also check the alignment with keyboard PCB and then remove it to give a glue time to cure. 

As for the TPU dampener (I don't use word “gasket”, since it means something else in keyboard community), cut the filament sections of required length, distribute the glue in groves using toothpick and then put them on the applied glue. I placed one section at the time and held for few seconds so it would stay flat. Try to not cover the whole TPU perimeter with the glue, since it would make it more brutal and won't “stick” to the desk as well. If you will get some white marks from the glue after curing, you can just use alcohol and cotton swab to remove them afterwards.  

UPDATE: I also added printed TPU dampener version as well, for people that would rather print it than cut raw filament. 

Tips:

• Inserts in electronics enclosure model model are raised a bit (as shown in the picture) by design - without them that part was flexing upwards unnecessarily. 

• I also added STEP file if someone would like to make some modifications etc.

• Screw holes for non-heat-set inserts versions are 1.8mm. It can be adjusted using 
  hole compensation setting in Orca Slicer. 

• Print without supports
