This was just a very slight modification to an already great design.
I didn't feel like messing with the top screw of the printer, therefore I deleted the top leg of the clip and added fillets to the base of the remaining two legs for added strength. The print came out looking great and feels sturdy enough. If your wheel spins freely, there is very little force exerted on the clip.
I added the step file in case anybody wants to adjust the model in any way.
The author remixed this model.
