The original design didn't fit on my Antilop legs for whatever reason. My legs have a slight bend at the top so maybe that was the problem. This design needs some sort of fastener below it in order for it not to slide down. I'll be trying o rings as those are used in all of the amazon footrests. If that doesn't work then a hose fastener should have no problem. I only modified one side of the footrest, so you'll need to mirror the part in your slicer for the other side. I used the original joiner as well.
The author remixed this model.
This is a remix of Antilop Footrest from Tom Ewig but with a slit to allow the footrest to slide onto the legs easier.
