crkbd case with standoffs

This is a remixing from https://github.com/Lenbok/scad-keyboard-cases/tree/master/crkbd

I modified this case because i don't like the tenting elevation in the case. Also i added a some standoffs inside the case and trim the usb port and jack 3.5 because collide with the case wall when you put inside the pbc already soldered.

To print the case, i strongly reccomend use the infill at 100% to make the more harder the case. Otherwise with the base, i used a clear fillament with the infill at 10%
