bearingless x & z axis Prusa i3

thingiverse

This set of designs replaces the X carriage and Z-axis ends with bearingless parts, also providing a quick change ability for extruder types. The z-axis parts are designed to be used in conjunction with a z-axis wobble fix. The belts are attached to the carriage by inserting the ends into the slot and clamping them in place with two 3mm bolts (see picture). The various extruder mount options are fixed to the carriage by sliding them on and securing with 3mm bolts top & bottom (see picture). I also include the "wobble fix" design, but it's worth noting that this was designed for a 3-bolt brass lead screw nut so may not be applicable to your own hardware. However, other 4-bolt and i3 wobble fixes can be used just as easily. An additional extruder type (non-e3d long range bowden) design is currently being finalized but will not be published until it has undergone thorough testing, after which it will become available on this Thing with a list of any additional hardware requirements. 14/03/2018 Long-range non-e3d bowden mount added. "This mount requires a single alu mounting block and will work with mk7/8/10 heating blocks and throats.
