Equitorial Mount Mk2

thingiverse

This is my revised equatorial mount designed for 3D printing. I've made significant changes to ensure accuracy and functionality. Even with high-infill plastic parts, you can achieve excellent results. The design takes inspiration from high-end equitorial mounts costing over $5000, featuring 1.5-inch diameter steel shafts as the primary axis of rotation. I've included step files for all components, allowing you to modify them according to your needs. You don't need to use heavy 40-pound steel shafts; instead, opt for lighter 3/4-inch shafts if desired. This design is intended as a starting point for your project rather than a complete solution. I'm currently working on stepper motor mounts and gearing, which I'll upload once completed. Hopefully, I can integrate a Raspberry Pi with indilib.org to control the system. The printable components include: 1x DecArm.stl 1x RA Axis.stl 2x Adjusting Arms.stl You'll need to cut the following parts from sheet stock (I used 1/4-inch aluminum plate): 1x .25 alum base To complete the project, purchase the following items: 1x Shaft 1.5"x18" 1x Shaft 1.5"x12" 2x Shaft 1.5"x3" ~10x Oil-embedded sleeve bushing 1.5"ID 1.75"OD 0.5"L Epoxy for gluing bushings Bolts with fender washers to secure the RA Axis to Adjusting Arms Bolts to attach Adjusting Arms to Base Tap for bolts (I used 5/16) Shaft collars for shafts Design or find the following components: 1x Shaft to Telescope Adapter For a fully 3D printed version, consider using lightweight shafts and finding a suitable balance weight. A lightweight conduit could work as a balancing solution. I'm planning an assembly guide and possibly a video tutorial in the future.
