SideTS (Remix)

Original seemed decent for the most part, but I didn't want to add supports to print the holes, so I made a (somewhat) quick modification to remove the need for that (comparison of the original to the modified version in the images).

To get both sides, duplicate/clone etc. and mirror (preferably along the X axis) once in the slicer

Offset the holes and added some cross supports so they could be printed without any additional support
