This is a remix of a nicely done comfortable handle for using hex shaft quick change tools by hand. It has a spinner top for applying constant pressure while rotating the tool. It still has the original “Stubbs” click-in retention finger with the addition of a hole for a 6 mm M3 cap head for a firmer lock. See below for discussion of the different positions of these bit retainers.
I am using this with a Jacobs 30248D Adapt-A-Drive Chuck as a large (¼") pin vise as shown in the picture. This has the groove for locking the hex shaft in place at 13 mm from the end. However, the original design has the retention finger at about 16.5 mm into the handle. This works fine with all my DeWalt quick change tool bits, but not with the Jacobs chuck. Rather than try to move the retention finger, I simply added the M3 locking screw because I also wanted a very tight connection to the chuck. Of course, you can skip the M3 screw if you don't need it.
Print Settings:
Print the handle with the spinner end down. You will want supports to the build plate only.
Spinner cap should be printed open end up, probably ok with no supports (only the top edge fillet is an issue). It clicks onto the handle and spins smoothly once you get all the handle supports removed cleanly.
Use PETG for strength with extra wall thicknesses. See the original model description for more suggestions.
