Wire Dispenser for BNTechGo, Remington Spools

This is a remix of the excellent Cable Spool Holder Gridfinity.  I have scaled this down to fit BNTechGo spools, which are around 65mm in diameter and 61mm long.  I have also created end caps to attach to Remington spools (~55x57) so that they can also be used with the same frame.  The gridfinity stuff is removed, as scaling destroys the standard and also I don't use it.  I like it though, looks neat.  Corner holes are 4.2mm to fit MM#94459A140 or similar heat nutserts for M3 flathead screws.  There is no winding mechanism, as this is intended for loading full spools.  That's it, nothing fancy.  It's better than the box full o' holes or the tangle-tinsel tree if you've got some old filament you want to get rid of.  The original model is great if you need to wind your own spools.  Careful if using a power drill to wind- there are no bearings so your printed parts will heat up/abrade from the friction.  Definitely give that model a like.

You can also skip the inserts and use 1/4" or 3/4" #8 sheet metal screws.  Widening the holes and the countersink on the side plates first is a good idea to prevent cracking, but the holes in the large bodies themselves work fine with #8 threads.

STL is a plate export with the parts oriented.  Any filament is fine.  I've used ASA, ABS, PETG and PLA so far.  There is a ton of clearance everywhere, nothing on this needs to be precise.

-If you import the assembly as a single object made of parts and orient the side of the cube on the plate such that the open claw or the wire grabber corner faces upward, you can simply delete the upper side piece and print the remaining parts as one object.  Just allow supports from bed only to cover the small overhang on the edge.  That will easily save 30 minutes of print time for each unit, as well as save half the screws and inserts.

There is only a partial history (post-import) in the .f3d.  I had to pull this version out of a huge file of a bunch of other tests, so some stuff may be missing.  If you need to mod you can always pull in the OPs model to compare.  The scale is roughly 0.835 Z+Y, X is mostly 1:1, just a few press-pull mods and interference fixes.

There are two versions of the Remington -> BNTech adapter caps - v2 is for filaments that can bounce, like ASA, v1 is for garbage like PLA.
