DIY Articulating Arm

thingiverse

This custom articulating arm is a scaled-up version of the NOGA articulating arm commonly used for dial indicators and camera mounting. I aimed to create an enlarged model utilizing hardware store parts for standard features and 3D printing (no supports required) for unique components. The design also incorporates a swiveling feature, achieved by crafting two 3D printed elements that form an inner and outer 'bearing' race. Unprinted filament pieces serve as the bearing, inserted from outside the part assembly. For those who wish to modify or convert the design to metric units, I have included the STP file. The design is based on US standards for PVC plumbing, hardware, and dimensional lumber. Sourcing good quality wooden dowels with accurate diameters proved to be the most challenging aspect of the design process.
