thingiverse

Update 2014-10-26: Modified Belt Clamp, Expanded to Fit Modified X-Carriage: Modified for use with Igus RJMP-01-08 linear bushings on 8mm rods, rod distance is set at 45mm. Modified Belt Clamp: Updated spacing between Belts, now 13mm apart. Extended Mountplate: Designed to fit standard Prusa i3 X-Carriage - tested on my modified X-Carriage. Stand-Alone Bowden J-Head Mounting: Ability to mount two bowden J-Heads for convenient operation. Topplate, Switchflag and Servobracket: Printed out and assembled, but yet untested. Features a standard Hitec HS-55 Micro-Servo (slightly smaller than the 9g noname servo) and optical endswitch. Planned Features: Automated bed-leveling using a clip-in 9g servo and optical switch, probe driven through a dual-head mountplate. Dual bowden extruder setup mounting plate for added functionality. Single fan-mount option available upon checking Biomushrooms design. Cooling fan integration needed for effective heat dissipation. Motivation: As an owner of the Prusa i3 "Acrylic" model, upgrading essential components became necessary. Upon extensive research, only a few designs suited my needs - Biomushroom's design was an exception. Modification Rationale: My printer has unique belt placement, which wasn't accommodated by existing X-Carriage designs. This modification provides an adaptable solution.

Original Assembly Steps: 1. Use standard bolts for assembly. 2. Secure the carriage on the printer frame using M3 screws and nuts. 3. Install Servobracket, Switchflag, and optical endswitch components with ABS-acetone mix glueing. 4. Secure mounting plates using screws provided. Modified Carriage Components: * Modified Belt Clamp (original: to narrow) * Extended Mountplate for Dual-Bowden Extruder Setup * Servobracket/Switchflag for Bed-Auto Leveling
