Original Polargraph central axis Gondola kit
This is the gondola that comes with PolargraphSD machines. It consists of two arms that rotate around a central pen holding tube.
- Acrylic parts
- Brass tube
- Servo motor
- Pen grip
The tube itself is 16.5mm diameter, so is happy accomodating regular-sized slim pens. I include a 3d printed Jinjawhopper pen grip that is so good that I've even given up using blobs of blu-tack myself. I know, they said it would never happen.
The kit is unassembled. You can look at a video of assembly.
