Files

Model is shaped using Fusion 360 and original board 3D model from Sipeed:

https://dl.sipeed.com/shareURL/LICHEE/licheepi4a/05_3D_model

The model is cut in half in Prusa Slicer, you need Prusa Slicer to open the 3MF file. Models has been cut are also included in STL format.

Assembling

You need 4x M3*20 Hex Socket Head Cap Screws and 4x M3 square nut (Leftovers from Prusa mini), top part and bottom part will clamp the board. Screw length need at least 20mm long.

I printed using Prusa Mini with 0.4mm nozzle, in 0.2mm layer height speed mode, PolyLite PLA.

There may some bridge and loose strings in the hole placing M3 nuts, you can clear it with SL1.5 screw head and knives.

For with push button edition, make sure to turn the flat side of insert pin aligned with board, near screw one the flat side should face to screw hole.
