**Assembly Notes**
1. For Ceiling Mount Ball Bearings - so... 136 is the max you can fit in there, but putting less works. I haven't tested how low you can take that. But I'd guess I have about 100ish in mine and it moves great.
2. For connecting the two Arm Halves - There are 18 holes in each, but... like... depending on how heavy of equipment your putting on there, and how many arms your using (more arms = more length = more leverage), you can likely use much less, possibly down to 6.
3. Once installed and assembled, tighten the m6 lock nuts against the washer to the point where you can still articulate the arms, but they don't sag/fall on their own.
4. If the first Arms from the Ceiling Mount are sagging (you used lots of arms out at 90° angles, and you need more support, use 4mm shock cord from the shock cord plate, to the arm knuckle to support it.

**3D PRINTING SETTINGS**
For All Parts
4 walls
25% infill (honeycomb or cubic)

**For Parts With Printed Threads:**
0.08 layer height
0.42 line width
0.4mm nozzle

**For Parts Without Threads:**
0.20 layer height

**Material:**
My personal one is printed in Recycled PLA (from SunLu), so... I figure if that's stonk enough on this design, you should be able to print it from just about anything.
