Simple guitar string winder. I kept misplacing my store bought winder so decided to model one so I could just print one anytime I lost the last one. It does not include the acoustic peg puller as some winders have because I was not sure it would be strong enough with PLA. Prints in 2 parts - The Tuning Peg Cup, and the Handle. I use an M3 screw 18 to 20mm long to attach. Just use the M3 screw to self tap the hole in the handle and tighten to desired friction. I use a support blocker for the screw hole end of the handle to set the infill to 100%. I have included a 3mf file with the support blocker set this way and it also prints on a raft.
