Combined STL file with all parts

Separate STL files for each part

snes_spacer.stl is a small 3d printed spacer to relieve pressure from the pins of SNES clone console slot

n64sleeve.stl helps with aligning N64 cartridges if the clone slot is not long/wide enough

backplate_tabs.stl is the backplate that holds the Arduino

sd_spacer.stl or microsd_spacer hold the RGB led and fit between the SD card and the Cart Reader pcb (print with clear PLA/ABS)

sidewall_tabs.stl secures the Arduino Mega to the backplate with five M2x8 screws

case_xxx.stl are a replacement for the more simple backplate in case you prefer a full enclosure

The rest of the STL files are alternative designs in case you use the battery add-on.
