custom plug/cap for square or rectangular tube

Customizer OpenSCAD program to generate custom plugs and caps for square and rectangular tubing/pipe. Completely customizable in terms of tubing size and thickness with minor options controlling exterior appearance of cap, including length, straight or 45° edge (or a combination), and rounded corners.

This program can create a printable cap/plug for tubing from around 1/2" square up to the printers capacity (limited to 800mm X 800mm in the code), though supports may be needed if angled caps of extreme length are produced (it is possible to produce a cap that comes to a point).

While most input values which might break the program are filtered out, some extreme values could create some unexpected (but hopefully consistent) results. These results may be useful, but are not "guaranteed" to work or be printable, your mileage may vary.
