Rectangular Tube Internal Supports

Supports designed to be inserted in rectangular tubing to prevent the walls from crushing inward when tightening fasteners. The number of holes refers to the length of the internal support. Supports included for both 1/16" and 1/8" wall tubing. The holes are sized for #10 screws and are spaced on a ½" grid pattern to work with common FRC punched tubing. Adjust the quantity of internal supports by changing the number of "copies in a plate" before printing. Looking for Rev MAXTube Internal Supports? See here: https://makerworld.com/en/models/563576
