Oxwall Suction-Mount Vice - TPU resilient jaw covers. Now includes STL for crank end caps.

I picked up this old 2-in-1 swivel-jaw vice at a tool sale for a couple of quid. It was very rusty so the first job was to dismantle it and give it a good clean, dress the anvil section and the jaws, lube it up with PTFE and put it back together. I even managed to revive the suction pad which was unbroken but a bit dry, rubbed in a couple of drops of olive oil and, when absorbed, the suction pad started working again!

I'd already designed and printed the TPU end caps for the front crank and the suction locking handle - that's the End Caps STL also included here. 

Designed to be printed in TPU, I used Eryone Clear Shore95A (that's the only TPU I've got), 0.2mm layers, 0.4mm nozzle. Very slowly, I used 10mm/s for the first layer, 20mm/s after that, as the jaw is printed with the jaw face on the printbed and is a mass of tiny islands, always a challenge for 3D printing :o) I also raised the temp of the printbed a fraction to 30C from my usual cold PEI textured bed because the first prototype lifted in one corner, I didn't have any problems at 30C and it didn't bond permanently to the PEI, phew, I think that can happen at higher temperatures.

Print with enough walls so that the 1.25mm collar is all walls, that's 3 walls at 0.4mm nozzle.

Print with enough bottoms to make the jaw face solid - I just set 8 tops and 8 bottoms for my 0.2mm layers and that did the trick. Alternatively if you want more compressible jaws you could set fewer tops/bottoms and allow some infill at your chosen %.

The jaws are at a funky angle - about 6deg, so I added a little pip which marks the bottom of the jaw. Print two of each size jaw and mount them with the pips downwards and they'll be the correct way up.

Hope this comes in handy for someone else.
