Horizontal pulley tensionner

Here's another pulley tensionner. This one is for a belt set in the horizontal way. The tensionner itself is fixed on the extrusion with inserts and M3 bolts. The pulley has a diameter designed for a 26 mm ball bearing. You can replace the stl rod by a M10 x 25mm long threaded rod.

Parts needed:
-26 mm (outer diameter) ball bearing
-2x M3 bolts
-Extrusions inserts (can be 3d printed)
-10 mm threaded rod with a 25 mm lenght (this part is optional)
