Arduino UNO Mounting Frame (.stl file for 3D Printing):
This is a mounting frame for an Arduino UNO board. Simply attach the frame to your next project using 4-40 flat head screws or with glue. The UNO mounts to the frame via threaded inserts and 4-40 mounting screws (see resources below for links).
The frame measures 2.2 x 2.35 inches and provides a convenient wire routing clearance of 0.22 inches under the Arduino UNO.
Recommend 3D printing the frame in 'Durable Plastic'. This will provide a rigid, secure mounting.
