Snatch Block Pulley with Badge Tether Attachment Block.

I wanted a smoothly rolling pulley for my ubmillical… so now I have one.  I modeled this to use an old belt pulley wheel from the tronxy x5s that I have since torn down.  Print 2, supports will be needed.  Use an m5x24 bolt with a nylon lock nut.  (Make sure not to tighten it too much or it won't roll very easily.)  Assemble as shown in the picture.  I used a zip-tie to attach the small end to the triangle on my badge holder.Also including a block to attach the badge tether to the 2020 extrusion.  This part uses an M3 screw and hammer head t-nut.
