TTTTTT: TITAN Tiny T5 Timing-belt Tension Tightener by Daid Oct 6, 2012

Description

A belt tension block, used to attach the ends of 2 T5 timing belts together, and screw them towards each other so the belt is tight.

I designed these for my TITAN machine, which is the smallest 3D printer up-to-date. But not finished. Still, I wanted to share the tension blocks, as they are smaller and easier to use then most other systems.

My TITAN development can be followed at: github.com/daid/TITAN

Short belts are simple, unscrew the motor, push it down with force while screwing it down tightly. Also make sure the pulleys and belts line up, unalignment here causes problems.
This won't fit very well on a UM, as the UM doesn't use T5 timing belts. I'm using the wave tensioners myself, but the easiest solution is a lot easier. Replace the 10mm bolts in the claws with 12mm and an extra nut: http://wiki.ultimaker.com/Ultimaker_rev.3_assembly:_X-Y_axes#Step_3:_The_claws this really helps on the long belt tension.

Instructions

1) Print twice for each belt.
2) Grab 2 M3x25 screws.
3) Attach both blocks to each end of the belt
4) Make sure the blocks are mirrored, one should have the belt in from the left side, the other from the right.
5) Screw in the M3 screw on the open side, this should screw the first part, and be lose in the 2nd part.
6) Now screw in the other M3 screw, this should fall in the closed end of the first block, and screw into the 2nd.
7) Thighten up the blocks with the 2nd screw. Add nuts to make sure everything stays together.
hey Daid, are you currently using this on your UM?? I have backlash and tried everything to get the right belt tension. Thanks!!! BTW your question box is awesome!
