This is a bracket and hooks to hang two pairs of shoes off the back of a Peloton exercise bike (model: Bike, not sure if it will fit the Bike+) Full supports helpful for printing.
There are three parts: one is a frame that attaches to the aluminum extrusion on which the saddle slides, and two hooks that hang from it. The hooks print flat on the print bed (though they're not symmetrical, so be sure to put the flat side down). The main frame prints best with the “horizontal crossbar” pointed up (so the part that attaches to the aluminum extrusion is flat on the build surface).
Edit: A number of makers have reported that printing this model at 102% scale allowed for an easier fit on their bikes; presumably the powder coating is thicker on some bikes than others. YMMV. I've added a PrusaSlicer *.3mf file which has the hanger pre-scaled to 101.5%, as well as both hooks (unscaled, though you may want to adjust), along with supports and print settings.
To install—at least on the Bike model—the plastic cap covering the aluminum extrusion needs to be temporarily removed in order to slide on the frame (requires a screwdriver). It can be put back once the frame is on.
To help others interested in this model: if you make this, please post a make with photos and the print settings that worked for you.
