Customizable spider core (1-30 arms)
thingiverse
I designed n-arm spider arm core inspired by tour's 6-arm design (Customisable Rubik's cube core, thing 1676041 by tour). Several customization options are available through parameters like this: The number of arms and orientation can be changed. All corner turning platonic and archimedean solids layouts will be available. Currently, I have implemented 1,2,3,4,5,6,7abc, 8ab,12,14,20ab and 30 arm shapes. You can customize the stem length (Length_of_Arm), stem thickness (Diameter_of_arms), core ball diameter (Diameter_Inner_Sphere) and curvature of stem endings. You can also add counterscrews & Screw hole diameters, hollow centre (Diameter_Hollowed_Inner_Shpere) or symmetrical Half core (Make_two_halve_spheres). My TODO list includes: Fix bugs, please comment if you find any more. I also want to add options for surface turning connections and stem curvature with sphere centre away from the centre. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator (5th Generation) Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.15 Infill: 20% Notes: Supports or not depend on layout. With full core, I suggest to use supports when printing in one piece. Normally with half sphere, you do not need supports. How I Designed This Openscad
