Hand Grip for standard 3/4" (U.S. size) PVC pipe

A simple hand grip that slips on and clamps onto standard U.S. / North American sized ¾" PVC pipe. It is also designed to be tightened using a 1.75" or 2" long ¼-20 bolt, nut and washer. I recommend printing in a softer material like TPU to resist breakage when tightening the clamping mechanism. 

I designed it with an optional large flange for my use case with roll of pallet shrink-wrap. It stops the roll from rubbing your hands when it spins.

To assemble:

1. Glue the optional wide flange onto the main grip if you want it.
2. Insert the nut into the recess on the small wedge. Optionally if you have a ¼-20 flange nut (see images) I find using those upside down spreads the pressure and greatly assists in being able to tighten the grip without damaging the wedge. 
3. Drop the assembled wedge and nut into the grip wedge side facing in.
4. Put a washer on the bolt to spread clamping force and prevent the bolt head from digging into the handle material.
5. Insert the bolt through the hole in the end of the grip and thread it into the nut on the wedge. Tighten it finger tight for now.
6. Slide the assembled grip onto the PVC pipe until it seats all the way down.
7. Tighten the bolt while holding the grip still. It will take a fair amount of force to create a solid lock onto the PVC.
