Case for arduino uno & DB25 LPT port board for use with GRBL Software

thingiverse

The case is made for an arduino uno board and one of the common DB25 breakout boards that can be found on ebay (for example) I designed the Case for this two components to easily interface the Arduino with grbl firmware to cnc hardware controlled via common parallel port interface. Print Settings Printer: Duplictaor 4 Rafts: Yes Supports: No Resolution: 0.2mm Infill: 100% Notes: I printed the box with 100% infill and 0.2mm layer height. But since there are no critical geometries you should not have much problems printing both parts with other settings. I also used a raft to achieve a homogeneous surface. Post-Printing M3 tap drilling of the bottom shell. The case can be closed with m3x20 countersunk screws. So you have to tap m3 threads into the bottom shell bore holes and maybe fix the top shell holes with a 3mm drill
