Delta Arm jig

thingiverse

This is a jig to make your delta arms with carbon tubes, 6mm o/d, and 10mm stainless steel balls. The concept involves screwing these to your workbench or wood. Instruction: Screw into a flat surface on your workbench to create a level line using a square, then measure the distance you want from the centre of the steel ball. Measure 62.5mm along both lines and draw a line joining them to form a stretched-out H shape. Line up the corners of the triangle tabs so they match the same lines, then screw them down. This design hasn't been tested or printed, so I've left the raw FreeCAD file and STL for anyone to remix it. Have fun and share your remixed versions. Print Settings: Printer Brand: RepRap Printer: Prusa i3 Rafts: No Supports: No Resolution: 0.35mm Infill: 20+ Notes: I printed it with 10% infill, which was a big mistake - when the ball holes started to print, there was nothing to support them. How I Designed This: I designed this using FreeCAD, combining sketch and boolean operations.
