Trolley lower bar replacement for Gotway ACM 16

This is a replacement part for the original trolley of a monowheel Gotway ACM 16

I realized a different bottom hook to replace the thin aluminum bar of the trolley (very light and weak) to have something more robust and aesthetically nicer.

Edit 5/04/17: Added a new version, with the rest support. Now the wheel can stand alone, without having to rest against a wall.

Edit 13/06/2018: Update; I added two new files, they replace the previous version "with support". I have strengthened it considerably, to better withstand shocks on the trolley.
There are 2 versions. They differ just in the width of the pads, the wide version most suitable for keeping the wheel standing on uneven surfaces.

Edit 25/06/2018: Tested and modified the Large pad version, now fit better on the wheel.
I unified the two models in this one, I recommend this version.

Edit 20/01/2021: Replaced all versions with a new stronger one (rev 2)
