My wife needed a new pincushion for het sewing room, so I create simple design for a magnetic pincushion. She liked so made several other for her. She can throw the pin into the holder
The design requires ½ inch diameter magnet no thicker than 5/16 inch.
Print with .4 nozzle at .20 layer height.
I attached the FreeCAD model containing the cross sectional sketch used in the additive rotation. There is just two layers of plastic above the magnet, i.e., thin as possible.
The author marked this model as their own original creation.
