The file 'FlSun Delta Strong And Simple Carriage (GT2 Belt) 3D Printer Model' is (stl) file type, size is 45.2KB.
Most of the carriages available for delta's with linear rails have little posts around which the belts get looped to then lock onto themselves.
I got fed up with (1) these posts breaking off when tensioning the belts or after a few days of use and (2) trying to pre-tension the belt properly when installing and failing miserably.
It looked like https://www.thingiverse.com/thing:818954 would fit the bill. However, the belt would slide out of the slot too easily, so I decided to make my own design.
Slots fit very snugly and I use self-tapping M3 screws to attach the links to avoid having to incorporate slots for M3 nuts. Regular M3 bols (without nuts may also work).
