Idea
This model's idea is a rebuilt and (hopefully) improved version of: https://www.thingiverse.com/thing:3964197
While I liked the original model and for this version used most of its measurements, I had a few issues with it and even my heavily used print is essentially a modified version. Time to learn Fusion 360 and set a few goals:
- Threaded inserts in most parts, where an inserted nut would be a hassle
- The whole build should be straightforward to assemble
- Countermeasures to prevent something coming loose out in the field, in the worst case after polar alignment.
I'm not sure I'm 100% happy with my version yet, so feel free to suggest improvements! (and it's not been out in the field yet)
Parts needed
- 4 Screws M4x20mm (DIN 912)
- 4 Threaded inserts M4
- 3 Screws M3x8mm (DIN912; many other M3 screws should work, even longer ones)
- 3 Threaded inserts M3
- 1 M10 nut (DIN 934)
- 1 Screw UNC 3/8" x ¾"
Printing
- Use additional perimeters for increased part strength
- Supports only for the hexagonal cutout for the M10 nut
Assembly
- Properly seat the threaded insert into the bigger part. M3 from one side, M4 from the other.
- Fasten the bigger part to the Star Adventurer Base with the ¾" bolt.
- The M3 bolts on the perimeter are only there to lessen the chance of the ¾" bolt coming loose and to prevent the whole mount from turning, so use only a minimum amount of torque!
- Insert the M10 nut into the cutout (don't worry if it seems a millimeter too thick) and tighten the smaller part to the bigger one with the M4 bolts.
- Put all this on top of the EQ5 tripod and assemble the rest as usual.
