Adjustable Delta belt block

thingiverse

I am designing a large Delta printer and it uses larger GT2 belts and almost 12 feet per rail. I needed a tensioner that was longer with a long adjustment. With a M3x50mm bolt, the entire adjustment area can be used for tightening the belt. Since I use Openrails for all my motion, this is setup for the universal gantry plate. https://openbuildspartstore.com/v-slot-gantry-plate-universal/
