Kossel Delta Rod End Arms (using 10mm steel balls)

thingiverse

I designed a rod end arm for delta printers. It can work with the mini kossel, and you can modify it for other models. The space between two rods is 210mm, but this value is easily changed in the scad files. There are three types of arms available. One connects the rod ends using a solid carbon fiber tube (4mm OD). Another option uses interlocking printed parts that hold together when connected to the rod ends. A full-length rod arm makes up the last option. Take a look at this video showcasing a printer that uses these rods: https://www.youtube.com/watch?v=KjMJ3gn0HSk Here are the printing settings used for the arm: Printer brand: RepRap Printer model: Mini Kossel Raft preference: Not important Support preference: Unnecessary Layer resolution: 0.2 Infill level: 40% When using the rod end arm, make sure to adjust these settings if your printer has trouble printing tight or loose rods. Assembly and Printing Post-processing Solid carbon fiber rods require 160mm lengths with an OD of 4mm for assembly. Make use of a jig during assembly to ensure uniformity among arms. Assemble parts using M3 screws. Allow the middle section to cool after printing, preventing warping issues. A three-part arm system is also available, utilizing printed interlocking parts. Full-printed rods cannot be created on a mini kossel; however, cartesian or larger delta printers can do so. Once again, ensure that the part cools before removing it from the bed to prevent warping.
