i3 X-carriage for LM8UU with 45mm rod center-to-center
thingiverse
This is a unique X-carriage design inspired by other carriages found on the Thingiverse platform, specifically http://www.thingiverse.com/thing:889407 and http://www.thingiverse.com/thing:1103976. While these designs are excellent, I opted to create this carriage in FreeCad for easier modification. The sources used in this design are included. The linear bearings (LM8UU) are secured with zipties. A "teardrop" loop fastens the belt. This X-carriage is compatible with the standard i3 rework 4mm mounting holes, arranged in a 2 by 2 configuration with 23mm spacing. The rod's center-to-center distance is 45mm, and its diameter is 8mm. At this point, the design remains untested. Print Settings: Printer: Acrylic M-505 printer Rafts: No rafts are used. Supports: Supports are not required for this print. Resolution: Layers are printed at a resolution of 0.3mm. Infill: The infill pattern is set to 30% hexagonal. Notes: This design uses a 0.4mm nozzle and an extrusion width of 0.48mm.
