Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:1090240. Did this customized version for a couple of reasons i. My GT2 belt's bootleg tensioner using a clothespin spring is bulky 2. The tensioner mentioned above ( it looks really ghetto BTW) makes the otherwise clean machine look like some meth head's attempt at 3d printing because they thought you can make meth with it c.I was too lazy to salvage some lego from my bins IV.I got bored FIVE!. CONGRATULATIONS IF YOU READ THIS FAR, HAVE A COOKIE
