Low Budget Enclosure Using Plastic Drain Pipe

A very l;ow budget general purpose end cap to create a cheap enclosure for projects.
Simply use a length of standard square 65mm UPVC drain pipe. Cut to length and 3d print the end caps.
Retain the endcaps however you choose. I use small self tapping screws or glue.

I have attached the FREECAD file so you can easily modify the design to fit other pipe sizes or add features such as holes or other cutouts.

The example has been printed on a very old worn-out Ultimaker Extended v3 which I rescued from a skip. You might get better results on a better printer.
