e3d Clone Wrench

10/15/2019 0950 Designed and added a torque assist, printing now at 25% gyroid. I swapped out my MPMD for e3d clones a while back (the current version is here: https://www.thingiverse.com/thing:3717404), previously I was using this one: https://www.thingiverse.com/thing:3641567. Heat creep has been the major issue I've encountered, and not being able to retract filament into the PTFE tube for color changes is a big problem. I didn't want to remove the mount just to fix it, so I came up with this solution. This wrench grabs the PTFE bowden connector while holding the heat block in place, allowing me to clear any jams without removing the mount. The e3d Clone bowden connector can be particularly tricky to remove, harder even than the threaded bowden connector - and that's saying something when it comes to removing PTFE. So this wrench was designed to slip over the PTFE tube and help make removal easier. I've only tested it with my not-installed e3d clone, but I imagine it should work just fine on an installed setup (that was the whole point of designing it). Do not use this wrench on a hot e3d clone. The wrench lock should be printed and fitted in place - it's not strictly necessary, but when testing with PLA+ it might bend or flex too much. I came up with that feature to prevent any flexibility issues. The wrench lock goes on the same way as everything else, but needs a rotation of 180 degrees for best results.
