Summary

Update 11/5/18: Added 1.5mm base to the thick version. 
Update 11/4/18: Added to thick version (+2mm thickness). 
Update 3/11/17 : New hole, added fillet. 
Update 10/23/16 : increased thickness for screw holder and legs.

A simple, adjustable belt tensioner + a belt tie to replace the cable tie. 
The tensioner requires an M3 screw. The screw hole is tight-fit and should provide more than enough tension to hold the screw. Designed to be printed at 100% scale.

Use higher wall line count (shells) & high infill for maximum strength.

The calibration cube in 3rd photo was printed @0.1mm layer height with properly tensioned belts and a Dual Z mod https://www.thingiverse.com/thing:2163949
