Pilot Metropolitan Fountain Pen Holder with Namiki ink cartiride holders

thingiverse

This is an effortless pen holder, carefully designed for the Pilot Metropolitan fountain pen (priced around $12-15) but it will also accommodate most thicker pens, pencils and markers with ease. Two versions are available, the original model which has a snug press fit that allows you to insert them firmly and even turn the device upside down without any cartridges falling out, while the other version features slightly looser cartridge holes making it more difficult to jam in the holder but still feels secure when doing so. Printer settings are unlikely to be crucial as this object is relatively simple to print. A brim or raft may provide additional support if needed. I intentionally left some space blank allowing users to customize the text if they plan to gift the entire bundle. Publishing the plain one seems like a likely outcome.
