Anet A8 Y Axis Belt Tensioner for GT2 Pulleys

I designed this Anet A8 Y Axis Belt tensioner for GT2 Aluminum Pulleys. You will need ø 5mm metal plug which fits directly into the 5,2mm hole(still tight enough) and inside the Pulley. See example links below. You can buy the metal plug in your lokal hardware store. This is where I found mines. They are simple parts to keep furnitures etc. together.

I printed at 30% infill. Don't use less cause this parts need to be stable. You will have to print:
Screw 1x
Plate 1x
Tensioner 2x
