Ender Belt Tensioner 1.3 - Ender-2 remix

Full credit to Shinzuriki for the original designs. https://www.thingiverse.com/thing:3270228 https://www.thingiverse.com/thing:3264177 I have taken the original designs and made the following modifications... **X Frame**: Notched the front side to allow for the hot end assembly to pass an extra 1cm or so before colliding. This should allow almost the entire build area to be used without compromising the strength of the frame itself. You'll still need to move/cut the plastic dressing fitted to the gantry from factory. **Y Frame**: As with the X, I have notched the top to allow for the heat bed carriage to move around an extra 3cm. This should allow for the use of the entire factory heat surface to be used in the Y axis, hopefully once more without compromising the strength of the frame. **X/Y Bolt**: I have rounded over the ends nearest the printer itself to allow for a little less tension to be applied or slightly shorter belts. It isn't much, but it may help some. I have also modified the bolt hole to have a 0.5mm high lip around the opening to prevent the bolt from grabbing the bearing if it's done up too tight. The original maker's logo has been removed to avoid confusion. **X/Y Nut**: Unmodified from the original. Ain't broke, don't fix. _None of these modifications should prevent use on an Ender-3._ For ease of use I have also included two different 5mm Allen Key designs you can use, since one is not included with the standard Creality kit. One is intended to be printed with the layers running up the hex part, the other with the layers across. I wouldn't recommend using these to remove the bolts from the factory fittings but they're quite adequate for installing them into these new frames. *Update 24/06/19: Rounded over the ends of the Bolt further. Should hopefully give another 1-2mm of minimum tension.
