X-carriage with fore & aft fan mounts

thingiverse

My take on this popular item to design. This time in Heekscad and this time with dual fan mounts fore and aft to maximise X axis travel. I have retained the same fan mount used on Jonas Kühling's carriage to suit existing fan holders. Uses 4 x LU8UU bearings held with my machine screw holders and set up for a T5 or XL belt. Also features a convenient loom anchor point to tidy up the wiring. Loosley based on many other carriages around at the moment but originally from the Mendel Prusa v2 by Josef Průša :) Instructions Print it out, uses 4 metres of 3mm PLA and will take about 3.5 hours to print. 0.35mm nozzle, 0.25 layer height, 2 perimeters, 2 layers, 25% fill and 45 degree fill angle. Set the extruder on the back 22.5 degree angle (not sure why we keep putting all the extruder holes in there - the back angle gives the best clearance). Two versions now: XC1 for the LM8UU linear bearings, and XC2 for the LME8UU bearings. Use one or two of these fan holders and VGA fans http://www.thingiverse.com/thing:29158
