Working on making a custom part whilst trying to minimise iteration and waste.  Stock part has two positions, so I made one that fills both positions as well.

Uploading so that others can check it out or modify for their own purposes, my 305mm^3 printer is cartesian, so whilst it is on klipper with input shaping and a bigger nozzle, each print is still going to take up to 12 hours for a full size nice quality version in PETG.

Step files included for comparison and modification.

Updated thanks to feedback, have made the slots bigger by pushing the walls back 1mm, have also included both chamfer and filleted versions.  Extended version is lengthened now and has been tested by @Fluttex_49039 so is more reliable as a template for customisation.
