Do you want a place for your pen to be stored and within reach on your desk? Well, this might be the solution you need.
Its a simple pen holder that requires no supports to be printed. It also has the option of being magnetic, using a 18mm diameter, 3mm thick magnet that is placed inside the holder whilst it is being printed. (Magnet should be placed inside when layer 20 has finished).
The exact magnets I used for mine are the Everhang 18mm Round Rare Earth Magnets - 3 Pack from Bunnings Warehouse.
