Description
Remix of Apollo100's great design. The single knob locking three joints at once is clever and I didn't touch it. Print everything except the clamp and ball from the original model.
The clamp is the only thing I changed. The original profile prints it upright which orients the stress along the layer lines. I broke two of them — one PETG, one ASA. I reoriented the clamp to print on its side and increased the perimeters to increase strength.
The ball is now also separate from the clamp. It simply slips down into a hole in the clamp and allows rotating the arm without loosening the other joints. It also lets you remove the arm quickly while leaving the clamp on the table when you need it out of the way.
Support removal tip: The supports inside the threaded section can be removed by threading them out — just spin them like a nut and they unscrew cleanly. Way easier than picking them out.
