Introducing RichRap's Quick-Fit X-Carriage for MendelMax 2.0! This accessory has been tried and tested with over 1000 hours of printing time on its V3.0 version. The MendelMax 2 may be great, but it lacked something - RichRap's fantastic Quick-Fit X-Carriage! With different nozzle setups and multiple extruders, this carriage gets a lot of use. For added rigidity, the V2.0 version has thickened the carriage to 6mm; adjust screw usage accordingly. The V2.0 update includes 2x 40mm fan mounts with screw holes, several zip-tie mounting points for 20 or 30mm fans, and an OSHW/Reprap logo for style and strength. The internal geometry has been resized to accommodate all-metal hotends like the E3D and Prusa V2. Left and right-handed versions are available depending on your preference and extruder orientation. The V3.0 update features a massive cleanup of the 3D mesh, marginal hole adjustments, and an enlarged central cutout hole for more fiddle room. The OSHW/teardrop logo has also been redesigned. Print settings include using RepRap printers with no rafts or supports, resolutions ranging from 0.1 to 0.4mm, and infill starting at 20% with 40% recommended. For structural parts, print with at least 40% infill, use 2 shells/perimeters, and optimize layer heights. To assemble, you'll need two M4 (13mm) 624 bearings, a 30-40mm M4 bolt depending on plate thickness, an M4 Nyloc nut and washers for the Quick-Fit Lever. Place the bolt, washer, bearing, another washer, and final bearing in the latch, then thread the latch through the X-carriage bearing and tighten into the captive nut. Don't forget to share your experiences using this carriage with nylon, PP, or PC materials!
