Rock On v3 Shadowline Gasket Mount Case

This is a design for the Rock On v3 by fingerpunch.xyz. It is gasket mounted and fastens with 6mm x 3mm magnets. The top prints in 3 parts and the base prints in 2 parts and will fit on an Ender 3 sized printer. The base also has small brakets for securing the two base pieces together. The brakets fasten with 6mm M2 screws and M2 hex nuts. 

The switch plate supports the encoders under the palms. The middle top piece also supports the encoder in the center of the mouse keys. There are also holes for M2 heatset inserts on the underside for securing the PCB to the switch plate. These are optional, but recommended, especially if you plan to use encoders. Pressing the encoder takes a lot of force and can separate the PCB from the switches if not properly secured.

The MCU needs to be mounted on the topside of the PCB with components face up and should be mounted as low as you can mount it while still using sockets. Readily available sockets from Amazon that are about 5mm tall when soldered to the PCB will be low enough.

The trackball housing accepts three 3.5mm bearings. Just press them in snug.

The base has recesses for 9mm round rubber feet.

M2 insert holes are 3.4mm in diameter, 3.8mm deep, and taper down to 2.8mm at the base of the hole. Any inserts with these approximate dimensions will work.
