UM2 UM2Go 8mm rods carriage for open GT2 belt

Information

UM2 UM2Go 8mm rods carriage for open GT2 belt

I wanted to use 8mm rods only for my UM2Go build so I took 1255-B2P-A (optimized for injection) part as a start and make 3d printed version. It uses 11mm outer diameter bronze bushings. belt length for UM2Go is 460mm. Leave 2 teeth outside of the locking loop.

Technical

ABS 3 perimeters (matters) 20% infill (does not matter much)

Thanks for the comment. I put belt loop before putting XY rods into bearings and then stretching the belt using rods. For some reason it works.

Looks like this could be useful for people with Ultimaker 3s if they somehow find the need to replace this part or use an open belt. Quite an elegant design, meshing the belt onto itself. It does make the tightness a bit coarse, but I guess someone can use it in conjunction with one of the other springy tensioners available on YouMagine.
