The author remixed this model.
I removed the skadis hooks, and added 4 inserts I mean its going to take up some room, might as well make sure its stays put.
UPDATE JULY 8TH 2024
I remodeled to use hex inserts that chamfer all the edges. I did this in freeCad 0.21.2 and provided FCstd files so you can change the HSW hex size to what you use.
