Belt Deflect-O-Meter

**An accurate and repeatable way to measure belt deflection and thus determine the tension in your printer belts.**

This project grew out of a mistake I made purchasing a "belt tensioner" from **AliExpress** for $20, which turned out to be just a cheap digital tire tread depth gauge and some (very poorly) printed parts with a few hair elastics as the "spring"... Suffice it to say, **it was hot garbage** as sold, but I was intent on making it useful.

Fast forward 3 weeks of design, I reverse engineered the main clip on part for the foot of the gauge, the rear slide clip and added some features:

- Now snap fits onto your gauge and has optional thru holes for permanent mounting with screws.
- Uses a compression spring for better reliability, repeatability.
- Rear slide clip has retention pin and screw for better mounting.
- Has a proper "normal" pin spacing of 50mm. (was 62.5 previously ?!?)
- Included STEP files for anyone who has a different fitting gauge and wants to mak
