Description

A printable belt tensioner, with a fitting for a M3 bolt and nut

Instructions

This is my first design and upload to thingiverse, please feel free to leave comments.

Update 24-06-2012: Redrawn in OpenScad, added a Ram and a lip to help stop Belt from jumping off. Also a 2 sided option is in the scad file based on IcanCwhatUsay derivative thingiverse.com/thing:16721 - Just change "number_of_sides" variable at the top of the file and Belt width can be changed with variable "belt_width"

I'm going to give this a go as the supplied y belt was a little too short to get purchase to tighten it. Might I suggest you fit 2 nuts tihgtened against one another, flush with the end of the screw, that way the pressure is spread more evenly across the width of the belt and should prevent any damage to the belt from prolongued use.

I like the idea and it would work great. When I saw your message I decided it was time to redo this and add a ram. might want to re download the file and give it a go. Thank you

Can you post a .DXF file instead of a SLDPRT please?

Thanks

I have added the dxf file, with every view I could add. Let me know if there is a problem with it.

Printed and using on Sells Mendel X belt, with the ram I posted about below I am pressing against the teeth of the belt instead of the back like you show. No choice for the Sells x axis, but it still works! I printed at 20% infill, but I recommend more, because the bottom layers aren't very thick.

yes! i was just thinking about some sort of tensioner like this. bravo!

Thav on January 24, 2012 said:

I like that this can go anywhere on the belt. Might consider adding a ram to avoid abrading the belt with vibration. See this derivative of some of the other tensioners. http://www.thingiverse.com/thi...

I Will definitely try add a ram soon then and see how it goes. thanks for the suggestion :)
