I recently got a Wahoo Kickr Core bike trainer. You need to use a couple spacer adapters in order to mount a thru axle bike on the trainer. These adapters are retained when a thru axle skewers them, but they're loose when you remove your bike. I didn't want to deal with keeping track of loose bits and bobs each time I took my bike off the trainer, so I designed a different bit or bob that I could lose instead… but if I don't lose it, it'll help keep the adapter pieces with the trainer.
I printed this with 3 thick perimeters (and a 0.8 mm nozzle) in PETG. I don't think the 3 perimeters is important, but I do think it's important you print this in PETG. It is a flexure, after all.
I've currently only validated this for 12x142 since that's what I'm running. I also included a 12x148 model but have no way to validate it - if you end up using this version, please let me know if it works!
Happy spinning!
Note: photo shows the V5 model; V6 has a bit more clearance for the flexure prongs to collapse inwards and a shallower lead-in angle. V7 was an update to the CAD file to make it easier to configure variables.
