3D model description

This is my version bowden x carriage and j-head mount for prusa mendel.

I based on http://www.thingiverse.com/thing:45883 (thank you for openscad file I reused).

My main plan was to create 2 X-carriage prusa mendel

main changes:

- allows symmetrical both side 2 X-carriage belts (see part: http://www.thingiverse.com/thing:128514)

- moved hotend 3.5cm higher

v6:

- easier mount of bowden tube

Update (10/19/2013) from v6

- issues with wobble and not tight grip on linear bearings forced me to create clamps to hold tight to bearing

-cutout for hotend cables.

Update (8/06/2013) - printed parts and assembly - pictures

Update (8/05/2013) from v5:

- separated bowden tube mount and j-head mount from carriage

Update (7/30/2013) from v3:

- moved up by another 1.5cm

- slim down design, better positioning of belt clamps, added one belt clamp

- fans mount straight

3D printing settings

Instructions:

1. print parts with support and clean up.

2. put carriage on 2 linear bearings and clamp them with screws

3. drill bowden tube size hole in top plate - bowden tube I used was 3/16 in OD and 1/8 in ID - you can modify the size in parameters on beginning of scad file.

4. put bowden tube through hole and screw on the M5 nut, bowden tube was little squeezed and couldn't pass 3mm filament easly - I used 1/8 in drill to adjust that.

5. assemble part with 4x M3-25mm screws with washers/nuts on bottom. 2 side plates slides into hotend holder. Slide M3 nuts into bottom plate mounts, they should attach quite well, so it will be easier to screw in.

6. mount carriage parts to bearings

7. mount 40mm fans onside

8. mount bowden + j-head mount to carriage with 4 nuts slided into holes in carriage and M3-25mm screws

9. attach belt clamp - I used http://www.thingiverse.com/thing:31482, need little work around with ziplocks becasue my belt wasn't that bold.

10. extruder mount is from thing: http://www.thingiverse.com/thing:25683

11. calibrate bed (z axis)

Improvements of v7?

- move belt on side bottom? (idea from: http://www.thingiverse.com/thing:22887)
