Easythreed X1 X-axis belt tensioner

thingiverse

Update: a version that can be printed in PLA can be found here: https://www.thingiverse.com/thing:4296030 This is a simple X-axis belt tensioner for the Easythreed X1 and X2. It can even be printed on the easythreed itself. All it requires two additional m3 nuts and two m3 bolts that are 12 to 20mm. How it works: This part replaces the panel that would normally hold the X-axis motor and rods. When tightened, the m3 bolts push the X-axis rods, tightening the drive belt. Print recommendations: -The part is designed to be printed with supports and a 0.2mm layer height. -The holes for the motor gear and screws have a sacrificial layer to improve print quality so you will need to poke something through the holes to open them. WARNING: Do not print in PLA. The stepper motor gets hotter than the glass transition temperature of PLA and makes it soften (I made the mistake with the first one I printed). If you intend to print this, make sure you do so in ABS!
