Platform/Belt holder for 2020 extrusion

I hate to re-print models when something breaks. Because of that, I have designed a belt holder/platform to create add-ons for 2020 extrusions. Just screw the add-on using M3 screw. The platform is secured to the extrusion using a M5x8 or M5x6 screw.

Design:
Designed with support-less in mind, after printing just cut off the bridging material. The model is meant to be printed with 0.2 mm layers. Securing it with a M5x6 will keep it in place if You use a M5x8 screw, it will also hold a belt that is inserted in the extrusion slot.

Add-on development:
There is standard hole spacing that can be used to develop new add-ons like end-stops, cable holders etc.

Options:
There is a model with M3x4 threaded inserts and one with smaller holes for self threading directly into the model.

Items needed:

• M5x6 mm (to keep it in place) or M5x8 mm (to hold belt),
• M5 screw nut for 2020 extrusion,
• *(Optional) M3x4 mm thread insert.
   

My add-ons:

• RepRap end stop holder
• PTFE cable guide
