Thanks for sharing this! I purchased a roll of flex filament from 3d-Solutech (via Amazon) and it worked great at first..then started to bind up on every print. I had success with your V3 design in combination with EricPrint's Printrbot NinjaFlex Pilot Upgrade. It did not seem to work at first but I trimmed off the lead portion of the filament that had jammed prior installing the mod. This also corrected an issue I was having with printing Taulman Bridge Nylon.

HI, if you made the top of the handle flat you could print without supports with better results.

Good point!
