Pipe Strap Wrench

Pipe Strap Wrench (for light/medium duty work)

I created this wrench to use around the house for odds and ends plumbing and other work. This wrench works really well for anything that is not perfectly smooth (Square/oblong shaped objects).  I had a little slippage on the PVC pipe until I tightened the strap it up a bit.  I might try to improve the texture on the strap in a future revision, but it still provides a good bit of torque.

Assembly

Strap

The strap simply slips into place.  See picture on what direction to insert the strap.  When in use, the friction and pressure of the strap cinches the slip on fitting to make sure the fitting does not release. 

Wrench

I highly recommend that you add reinforcing screws to the wrench.  

• 1 - M3-30mm screw to support strap mount
• 2 - M3-(40mm-50mm) screws to reinforce the wrench when applying force

Printing

• Print the wrench in a relatively strong material.  At the very lest, use PLA+.  I printed mine in PLA+ with 4 walls and 40% fill.
• Print the strap in TPU with 5 wall (effectively eliminating most of the fill), plus 40% fill for the fitting side.

** CAUTION ** 

I have not pushed this to it's breaking point!  

The wrench itself seems to be very rigid.  Therefore, the strap is the likely failure point when pushed to it's limits.   Use at your own risk.
