Delta Pinter Rod end and alternative Traxxas

thingiverse

This is an upgrade mod for two of these pieces. I find that using four screws or three screws for each diagonal rod makes the effector excessively heavy.\nI will now be utilizing only two screws for alternative Traxxas models (each one). \nTesting has been completed and I've used M3 Screws with 20mm (15mm is yet to be tested).\nI'm employing nylon nuts for enhanced locking capabilities. After completing the new delta, I'll upload some images.\nThe OpenScad (the reference is now included as a mod):\n//V3.2 of Nathan Stenzel's rod ends for sturdy stakes and the Rostock Max U-joint\nintersection(){\ndifference(){\n//The initial material of the prongs\ntranslate([0,0,17.5])cube(size=[18,8,22], center=true);\n//Removing some material\nunion(){\n//The axle hole\ntranslate([-10,0,24])rotate([90,0,90])cylinder(h=20, d=2.95, $fn=20);\n//The gap between the prongs\ntranslate([0,0,22])cube(size=[8.1,10,20], center=true);\n//The rounded part in the gap between the prongs\ntranslate([0,10,12])rotate([90,0,0])cylinder(h=20, d=8.25);\n}\n}\n//Trimming some off the corners of the prongs\ntranslate([0,0,15])sphere(r=15);\n//Trimming some off the bottom and top of the prongs\ntranslate([0,0,5])rotate([0,0,90])cylinder(h=26,r1=8, r2=8);\n}\n//Shaft\ntranslate([0,0,-13])cylinder(h=20, r=3.2, $fn=6 );\n//The narrower part of the shaft\ntranslate([0,0,-10])cylinder(h=2, r2=1.90, r1=1.5, $fn=15);\nOriginal files:\nhttp://www.thingiverse.com/thing:334094\nandhttp://www.thingiverse.com/thing:250786\n*** Following a mount test with a common effector, the size of connection was reduced and the screw is now located within the piece.\nPrint Settings\nPrinter Brand: \n Deltaprintr\n \n Printer: \n Deltaprintr Assembled\n \n Rafts: \n No\n \n Supports: \n Yes\n \n Resolution: \n High\n \n Infill: \n 25%\n \n Notes: \n I'm using PLA for all pieces.\nFor diagonal rods, I originally used aluminum tubes from gates.
