Summary

this is based off the Ultimaker Belt Tensioner 5000 by
Jamesm1 http://www.thingiverse.com/thing:19818

I remodeled it to allow maximum tension on the belts.
Allows room for more tension down the road by Opening up the mount holes. This is My first THING
and I seen other tensioners on here and this one fit the bill better than most. Very Firm grasp on the belt and with it you can Tune your belts to play music on (ok not that tense :) ) I may reprint them now that my accuracy has went through the roof. But the originals are doing very nicely.

Instructions

Print this 8x or use the second version (which has 8)
with this design you only have to remove 1 bolt and loosen the remaining 2 bolts(take off the nuts)

Once the nuts have been removed from the 2 bolts that are still in the block pull the bolts out about 1/3 of their length. Slip the Tensioner over the belt and then slide it over the bolts. Then add the 3rd bolt back in . Add the second Tensioner to the other side then add the nuts. Release the pulleys that are associated with that belt then with a flat object push either up or down to gain tension on the belt then tighten the nuts and bolts to hold the tensioner in place. In the future when you get some slack loosen up the bolts and repeat.

I am totally amazed by the accuracy that I got once this was done. AMAZING.

Please leave me any comments and Thanks again to Jamessm1 for the starting block for this. Good work .

Just added Installed Pictures.. There are 8 of these THINGS on my Ultimaker.

(re-modeled in LW 1mm=1m)

I put 2 on them there not knowing I probably could have gotten away with only one of them. But Im good for the future :) Im still doing minor calibrations and getting Happier and Happier with this Printer

You mount two of them on one block?
you must have had pretty slack belts..
on my machine i put one on each block and my belts were tight.

Sorry I ment to take pictures of this thingy and never did.. here are pictures It uses the original Bolts.. When I made it I was like OH NO this wont fit but with a little work it fit nicely .

Can you take a picture of it installed?  I don't see how it could be added without longer bolts.
