I recently decided to try out some alternative hotends for my Voron 2.4. Most needed a different carriage and removing the X carriage resulted in a fair amount of time retightening and retuning my belts. While there are already belt clamps, such as the StealthChanger BeltHelper and this Clamp, both require a lot of printing, hardware, and storage space for a helper with limited utility.  

My take is a dual set of 6mm belt grooves with a single hole. Most people will need to remove one of the 8mm SHCS from their X rail to use the clamp with a 16mm SHCS. I use a Fystec skeletonized extrusion so each hole has threading behind it, meaning I just need to locate two unused holes to attach the clamps. 

I printed in Hatchbox ABS with normal Voron print settings, but that is probably excessive.
