Card shuffler crank and handle

Family game night was saved using Spencer's crank model ( https://www.printables.com/model/872475-card-shuffler-crank-arm), but couldn't resist making a few usability tweaks! I shortened the main crank shaft a little because my hand kept hitting the table, but not too short to lose the extra torque from the original model. Rounded the edges a little more to make the crank a little more svelte and smoother on the hand. Scaled up the insert nub for better grip where it connects to the card shuffler (but still not great, maybe my shuffler is just worn out!). I also added a lengthened handle (not in the original model) that still fits on the original handle mount , but extended it, with a bit of a nub on the end for easier gripping and smoother shuffling. There are a lot of plastic manual shufflers out there, but if yours looks like the one pictured, this seems like a common model that this crank should fit!

I recommend printing in PETG for the extra durability (I used Polymaker Black PETG), placed on the bed as is in the 3MF file (the crank on its side, the handle standing up) with supports (I've used Snug and Grid and can't tell one is better).

I did a little fine grit dry sanding on the handle mount before assembling (just use the insertion nub as a handle and "reverse" crank to make it easier), to make it snap together more easily and found it spins very well after this!
