Magnetic Polargraph Pen Holder

thingiverse

Here is my magnetic pen holder for Polargraph gondola . I designed it to enable very quick pen exchange without losing any coordinate or making heavy movements to align the pen. It's really easy to attach and detach the pen very quickly and softly.

They must be inserted in the same position to define a correct plane, and leave 0.5mm over the plastic face. -Insert the bolts and screws to fix the pen. 1,000 thanks to Polargraph bigBoss Sandy for letting us introduce ourselves in this fantastic polar world!
