Strut channel trolley

This is a trolley for standard 1-5/8"x1-5/8" strut channel. There are versions for 6001 and 608 bearings- 28x12x8 and 22x8x7mm (ODxIDxW), respectively. They both have a 12mm hole through them to hang either a threaded eyelet or hook from.

As pictured, they have heavy duty bicycle wheel hooks- good for 70 pounds~~, but not yet load tested~~ (*see the end of this section for a load test update*). The hooks are from Home Depot- Husky 7/16 in x 8-1/2 in Black Bike Hangers. They have a wood thread that I partially filed a few threads down on and threaded with a die for a 3/8" machine screw. The nut secures pretty well at the end of the threads, but for better security/retention you can use thread locker, a locknut, or jam nut, though you may need to change the `NutThickness` parameter in the Fusion 360 model file to make more room for the latter 2 items.

The 6001 version is also pictured with a 21x12x5mm (ODxIDxThickness) thrust bearing so the hook can spin easily and not wear at the
