Re-spooler Gear Box for drills

For those who have re-spoolers with hand cranks, just add your drill with a 3/8" driver bit and this gear box to eliminate the hand cranking.

The re-spooler you downloaded probably has a drill option, but most drills will not line up directly and force you hold your drill up. With this gear box it will allow any drill chuck height within 100mm of the crank height and allow it to sit flat on the table.

This can be made compatible with most hand crank re-spoolers.

• I've included a large gear compatible with the 15mm shaft of the Fast Strong Easy Respooler by Tomik s Cuprou on Makerworld,
• a 12.85mm compatible gear for Spool Winder / Filament Umspuler by Dark28 on Creality Cloud and
• support for the 6.5mm crank shaft on the Strong Easy Fast Spool Respooler by Tomik s Cuprou on Makerworld.
• A blank large gear is included for anyone that wants to add a negative part in the slice to fit their re-spooler.

Just line up the larger gear with the crank shaft and the drill 3/8" bit to the small end.

I've printed this in PLA, PETG and PLA Case with PETG gears. Final model was all PETG. I don't really have a recommendation either way. I use mostly PETG so that is the way I went.

PETG at 240/75

5 wall to give the edges more strength.
