Tension Meter for the GT2 belts of i3 MK3S+ or Prusa MINI+

The model of the tension meter helps you control the tension on the belt of your Prusa printer.

It's specially designed to check the tension of your Prusa printer's belts. It works with Original Prusa i3 MK3/S/S+ with the belt GT2.

How to use it

Simply place the tension meter on the belt and check the deviation of the indicator whether the belt is correctly tightened (indicator between MIN - MAX), or too tight (indicator above MAX), or loose (indicator below MIN).

The model must be printed from Prusament PETG. It might not work properly with a different brand's filaments.

We offer g-codes only. It is because the print settings cannot be changed to keep the meter working properly.

You can change the print speed on the printer.

Print instructions

We offer g-codes for Original Prusa MK4, Original Prusa i3 MK3/S/S+, Prusa MINI, and Prusa MK2.5S/S+. 

For proper function use Prusament PETG.
