Enclosure for generic USBtinyISP board

thingiverse

I'm using a generic Arduino programmer USBtinyISP clone board for my enclosure, specifically the Deek-Robot model. It assembles quickly with no need for support material and prints smoothly in ABS plastic, although PLA should yield identical results. If you're feeling ambitious, consider adding light guides to your LEDs, which would likely require printing them flat so that the optical fibers run parallel to the board's axis. I haven't tried this approach myself. This design intentionally excludes access to the 10-pin connector and power jumper, both of which are probably not frequently utilized.
