These adjustable belt tensioners are a must-have upgrade if your printer does not already have easy belt adjustment provided as stock.

No more finicky belt tensioning, these easy swap belt tensioners are exactly what you need.

We do recommend purchasing new belts too, you may find the stock belts are of a lower grade and sometimes a little too short.


Material: aluminium alloy

Surface treatment: anodizing

Fits any printer with Y axis running on 40mm wide extrusion and X axis running on 20mm extrusion.
