This is my attempt of designing an enclosure for the brilliant Mewt project on GitHub: https://github.com/dakota-mewt/mewt
I went with the suggested components on the Mewt site and designed the enclosure to Match a 30mm button and the Arduino Pro Micro.
If you are looking for something else in terms of sizes, I have also included the Fusion 360 files so you can play around with them yourself.
Print Settings
Printer Brand:
Prusa
Printer:
Mk2.5s
Rafts:
No
Supports:
Yes
Resolution:
0.10
Infill:
20%
Filament:
Filamentum PLA
Notes:
I highly suggest printing with a 0.1mm layer height so that the rounded features are as smooth as possible.
You need to use some support material for the top part and I recommend a brim to keep the bottom stuck.I included the Prusa 3mf file that I used.
Post-Printing
Screw in the button in the top half. If you have the 30mm button, you can put the Pro Nano through the hole as it fits with all wires attached. Then use double-tape or hot glue to stick the Pro Nano to the bottom half in it's tray. I opted to connect the USB cable to the Nano and have the connector inside the housing.
I highly recommend joining the Mewt Discord here: https://discord.gg/FMm7zVdPhs
To connect the 2 halves, jus snap them together and they should stick by friction. At least it works for me, printed on my Prusa.
How I Designed This
I started the design with wanting an organic shape with rounded design features. The design of how the button is tightened demanded a wider plateau than originally planned, but overall I am happy with how it turned out. I planned to hot glue a few nuts into the bottom for added weight, but I am happy with how it is so decided not to do that anyway, but there is still room if you desire.
