Sony PRN C-41 Pen Hammer

I recently acquired a SONY PRN C-41 Plotter. It was quite popular in the 80s. Everything worked as expected, but the pen hammer was broken. This disallowed the correct printing, because the pen was not touching the paper.

I made this small 3D printed part to repair the head. It fits tightly into its position. In any case, the part must be glued with a small drop of cyanocrilate, applying it with great care in order to avoid jamming the head mechanism.

Printed using a XYZPrint Da Vinci Jr. with PLA, great detail mode (slow speed + 0.1 mm layers)
