About this 3D model

after having first successes with producing usable prints (after spending weeks on troubleshooting) with my mendel prusa bought as kit, i decided that the printer has (with little help of my brain ;) to produce better parts for it self at first. I am a fan of clever technical solutions, but a belt tensioner who drills a screw into the belt to keep it under tension, is in my mind kinda duct-tape-fix ;) So i made this one. Enjoy it or edit it as you like..
