Do you love your Miyoo Mini, but sometimes wish it was just ever so slightly bigger and more comfortable to hold? Me too. So I got my calipers out and measured my old Gameboy Pocket, and designed a grip to slide the Miyoo Mini into. You can still access all the ports/volume wheel as well.
Print it standing up, bottom of the grip with the hole for the ports on the print bed. I've included my gcode that I used as well. I printed this on 0.30mm layer height, in black PLA. It's nice and smooth and comfortable to hold, but the 0.30mm layers give it just a little bit of tactile feel so its not slippery.
