Sherbet gaming keypad

** Warning** I've made a couple of modifications to this since printing _and have not tested them_. I've added some clearance around the joystick so that it fits better, and the joystick cover now attaches with two screws instead of one. Assembly required filing and cutting in some places to make parts (really just the joystick) fit. I've tried to fix that in later designs but YMMV. I recommend printing individual sections of this design to test for fit prior to printing the whole thing, especially the joystick area, and a keyswitch socket or two. I was not able to get the heat set inserts in the wrist rest to align properly, and will be redesigning it with nuts instead. The joystick is not really usable without a way to keep the keyboard fixed in place, like a wrist rest that's fastened to the case, so this should not be considered ready to use yet. *I used:* * 24 Kailh choc switches and keycaps * 24 diodes * Third party joycon analog stick replacement. A first-party one ought to work as well. * 8x screws with threads suitable for plastic, roughly 1.6 - 2mm by about 6mm long, to hold the controller mount, usb breakout, joystick mount and joystick breakout board. * 6x m3 x 8-10 countersunk screws for the bottom cover. * 6x m3 heat-set threaded inserts for those screws. * 2x m4 x 20-25mm cap head screws for wrist rest * 2x m4 nuts for wrist rest slots (mine were 6.7mm W x 3mm H) * uxcell 6pin 0.5mm pitch to dip FFC breakout board. * Micro usb breakout module * Teensy LC controller * As compact and flexible a microusb cable as you can find to connect the controller to the USB breakout board. Case is a bit cramped. * Adhesive cork for the bottom * Wheel weights to add weight/friction Build log: https://www.billiam.org/2019/05/29/sherbet-an-ergonomic-keypad ## To-do list * Done ~~Use different method to secure wrist rest to case. Probably using slots in the bottom and regular m4 nuts.~~ * Done ~~Cut outs in case lip to fit m4 screw heads (for wrist rest)~~ * Additional clearance for joystick, maybe ## Updates **2019-07-18** * Added wrist rest with slots for captive m4 nuts, instead of heat inserts, which proved to be too hard to insert at the correct angle. * Added cutouts to case lip for better m4 screw clearance * Reoriented STLs
