This fits onto your drill to wind up load binder straps. It's specifically designed for the 50mm wide straps.

I printed in PLA but I used wall / top & bottom thickness at 2mm. Surprisingly it came out extremely strong. I have used it for 3 days at work and it seems very strong.

Print it with the flat side touching the bed, and a very small amount of supports is needed

A 10mm drill chuck is needed at minimum or the bit won't fit in the drill. If you need it smaller, let me know, but be aware this will make it weaker.

Enjoy!
