USBasp Case (USBasp 2.0) (adjusted version of http://www.thingiverse.com/thing:213544 according to ioanniskar measurements)Lid.STL has a tab that holds down the header, while Lid no tab.STL is completely plain on both sides. Use 3 x 2.5x10 or 3 x 2.9x10 self tapping screws to assemble the case. Regular M3x10 screws can be used as a last resort. The model has an integrated support for the bridge. It is an unconnected 0.5mm thin line that is very easy to snap and remove after the print is finished.
