Ovals-be-gone! Y-belt tightener for Printrbot by SVAPS. For T5 and T2.5 belts.
by SVAPS, published
Also I wanted the thing not to be too large or require too much ABS.
Added an STL for a T2.5 belt - I have not tested this, so please report any misbehavior.

The one labeled for 2.5mm seems to be for 2mm, and my printrbot LC
can't print with enough details to do the grabber right anyways :(
Hi there, sorry about the non reply after you posted the part, I've tested it now and it works perfect, I've been away from printing for some time.
Now I'm having a different problem the Y_tightener_Base breaks constantly from the pressure of the screwn :/ I'm already on my third print to replace, is there a way to reeinforce it?

Remove the mounting screws from the bed with the previous mount.
Place the base (green part) on the under-side of the bed with the rectangular tab facing away from you.
Thread the screws through the holes in the bed from above as before and through the holes in the base.
Grab the nobbly side of the belt with the nobbly side of the grabber (orange part) and slot the belt and grabber into the groove in the lid (Blue Part) with the smooth side of the belt against the long side of the groove.
Press the lid against the base and tighten the screws into the lid (Nuts should not even be necessary).
Insert and tighten an M4x40 or 50 mm into the grabber and keep tightening until your belt is taut.
- And you will have no more round holes come out as strange ovals :-)
