CL-260 Carriage

thingiverse

This is a replacement carriage for the CL-260 3D printer, engineered to utilize 12mm OD bearings from McMaster instead of the stock 11mm OD bearings that came with the original part, which were difficult to find. Two bearings are used per axis, totaling four, due to their relatively short length. These bearings can be sourced from: https://www.mcmaster.com/#6658k68/=15xyrzg Problems with print splitting and stripped holes for securing hotend stripping had plagued the first version of this carriage. To address these issues, I oversized those holes and inserted M3 threaded inserts into them. The threaded inserts used can be found at: http://www.banggood.com/100pcs-M34mm-H62-Brass-Knurl-Nuts-DIY-Accessories-p-971077.html?p=13251118846620130525 To install these inserts, follow this technique: Place the insert onto the tip of a soldering iron and push it into the hole in the 3D printed part as straight as possible until fully inserted. Next, quickly thread a screw all the way through the insert and then back it out again. This clears any plastic debris from the threads while they are still warm and soft. There are additional holes on the side of the carriage intended for attaching a bracket to hold either an inductive bed sensor or a dial indicator for bed leveling, but I have yet to test these features.
