I like the Ultimaker Belt Tensioner. But the curved edges put me off, so instead I derived this one from that.

After test fitting I ended up with a part that works on my GT2 belts and seems to have removed the belt hopping I was getting.


I printed this twice, both times I used a brim of 5mm and a fairly low speed. Turned out great.

I printed three of these in PLA two years ago for my DeltaMaker printer and they are still going strong! Great design!

I hear you on the round stuff, I find that printing without any shape or roundness yields a better and stronger print. Cheers to your design.

Works like a charm, sometimes the simple solutions are the best.

i dont get how this works? is this suppose to go under the pulleys when it prints corners? no matter where i put it it reaches a corner and it stucks.

very weak design, works for 5 mins, then even ABS will warp like you see in the made* pics.

Going to be using on our Universal laser systems kevlar belts and our dimension 1200es belts : p old belts = low quality prints : \

Worked great for me, I am now printing a 8-hour-job. I hope that the belt tensioners will keep their place ;)

I noticed that the x-axis works great, but the y-axis has a little issue: The tensioners are touching the top of the wooden case just a little bit. It seems as if the printer would do its job nicely, tough.

Everything printed fine, even if they are touching the top of the case. Thank you so much!
