RapMan 3.x Corner Set

thingiverse

Introducing a complete set of printable corners for your RapMan 3.x printer from Bits From Bytes! These strong replacements for the fragile standard acrylic corners can be installed without dismantling the entire machine, with most corners now requiring just three easily accessible bolts (down from eight) and no more tricky grub screws. The Z motor corner even includes a mechanism to adjust the tension on the Z belt, making it a one-handed operation instead of the previous three-handed task. The Y motor corner requires two files (top_backleft.stl, ymotor_clip.stl), while the Z motor corner needs four files (bottom_frontrightbackleft.stl, zmotor*.stl). All other corners are one file each, including top corners where bearing holders are integrated. These parts have been endurance-tested with a 24-hour non-stop print and continue to perform well; any weaknesses found will be addressed in updates to the STLs. Some STL auto-renders may appear mirrored but will correct upon download, tested in both BFB Axon and MiniMagics. Updates include v2 of some parts with corrected normals for improved slicing compatibility, and a new Z washer STL with a re-added hole. Most parts can be printed on standard FDM printers without supports using ABS material and basic settings, except for the Y motor corner's top_backleft.stl which requires support printing. For the Y and Z motor corners, note that the former requires support printing with cross-hatch 10% 'everywhere', while the latter needs a 70x8mm smooth rod from one of the top front corners for attaching the carriage to the plate. The Z motor plate will warp during printing but should be adjusted once mounted. Lastly, consider replacing the fragile standard Z pulley with a stronger design.
