These are based on upperpeninsulaplastics's Ultimate Retropie Joystick Controller. Thanks for providing a .step file!
These are the changes to my design:
I used a kit similar to this DIY Arcade controller kit. I've seen slight variations in the plate size and some controller boards have a USB type B socket
Rafts: No
Supports: No
Resolution: 0.2mm
Infill: 20%
Notes:
Print files as they are positioned, disabling auto-positioning in your slicer. The inlays should line up.
I don't have a multi-material printer, so I print the inlays first without skirt or brim or any other support that would get in the way, then set the temperature of the nozzle to PLA and change the filament with the bed still heating. Then I print the second file over the inlay, being careful to disable autoleveling for this second print, as the probe could potentially knock into or need to go down right over the inlay. Homing should be fine, unless you home over the inlay obviously.
[Obviously, this was designed before Prusa Slicer had pauses or filament changes... This should be much easier now]
