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

thingiverse

The project starts with an Arduino Uno board and a common DB25 breakout board that can be easily sourced on eBay for example. To create this interface, the Case is designed to easily pair the Arduino with grbl firmware to control CNC hardware through a parallel port interface. Print Settings Printer: Duplicator 4 Layer Details Rafts: Yes Supports: No Resolution: 0.2mm Infill: 100% Additional Information I chose to print the box with 100% infill and 0.2mm layer height for a smooth finish, but other settings should work fine since there are no critical shapes. Using a raft resulted in a uniform surface, which helps the box hold its shape. Assembly Drilling the bottom shell with an M3 tap will secure it to the top shell. Simply place countersunk screws into the holes on both parts and fix any loose spots by drilling 3mm pilot holes.
