Make jig have less overhangs and artifacts

[ProjectPatatoe]

I've noticed a few tweaks that can make the jig more printable by removing weird overhangs and less thin walls that don't seem to affect the functionality but greatly increased the printability for me. Some of these could be because of my PETG and 0.6 nozzle but should still improve things for anyone else. I tried to edit the openSCAD myself but struggled and ended up just forcing it via tinkercad+blender.

STL files are up on printables here: https://www.printables.com/model/1640587-gridflock-magnet-jig-tweaked

chamfered corners of the pusher to thicken the jig - removes thin walls / gapping

Straightened some geometry to prevent curved overhangs

Removed a flat overhang on the side

Great work, I've added a link to your jig to the readme. All of these changes make sense but some may be a difficult to implement in OpenSCAD. It's a good long-term goal to add those features to the scad as well, so that changes to GridFlock can also update the jig. But it's not super urgent, so I'll leave this issue open for now.
