For connecting two ends of GT2 2mm pitch timing belts together, such as are used on the MendelMax.

Have not tested it in operation yet, but printed in PLA I have to pull very hard to get it to fail.


Print and insert ends of belts. It is designed to be a tight fit so you might have to shove the belts in with a small flat screw driver.

I'm going to try to use this on a Rostock...the required belt lengths are extremely hard to source without paying exorbitant amounts...

It would be good to have two holes through the design, put a hole through belt with soldering iron and run a zip tie through both holes to clamp the print to the belts.

I think that's a good idea. Also, it would be nice to split the ends and have it joined using a tie wrap for tension adjustments. Someone please make it! :D

I prefer not to use zip ties for tensioning, I find that it adds springiness at higher speeds.

Oh, I see. However, that's debatable whether the extra springiness is beneficial or not. Anyways, I created what I described above. Check it out. And thanks for your work BTW. :D
