Strap Winder For Impact Driver/Drill

V2 IS NOW LIVE, CHECK WHAT PROFILE YOU PRINT. V2 HAS A FEW CHANGES, LARGER OD SLIGHTLY THICKER BASE, AND THE HEX BIT SITS .1IN DEEPER INTO THE MAIN BODY 

I have seen quite a few of these tools, and so far, none of them have worked the way I wanted. Either the backing was too small, or the ¼ impact bit wouldn't fit into the tool properly. 

I took all the things I had learned from trying to print other models and fixed them in mine. The adaptor fits nicely and snugly into the impact and locks in as it should. It also fits snugly into the winder, so glue isn't necessary for it to stay together. 

The ¼ Impact adaptor is replaceable and only takes 11 minutes to print on an A1 mini

I also added groves into it to make removing the strap after you wind it up easier 

The backing is just the right size and it doesn't take a lot of material to print 

PLA Works fine for this, it is plenty strong with the way I have my profile setup

PETG would be better long term but if you don't have any available PLA works great 

If you have any suggestions on ways to improve this design or want one for the bigger 2 in straps just comment and I can make that happen. 

Disclaimer: Please de-bur the impact adaptor before attempting to insert  your driver, the burr on the bottom could cause it to get stuck and break off if not removed, once removed this is not an issue (Image below shows what to deburr)
