- Molotow produces are great, Lego-like System of Pens
- The pens have a screw threat on one end which allows them to be custom filled
- I want to have a Pen shaft with two screw threats – one on each end
- I imagine this to be a case for 3D-printing but have zero experience myself and currently no time at all to get into it
- I can send one of those pens to
- who can make a pen shaft with two screw threat ends
- who can send me some copies of the custom shaft
- who can send me the file in standard formats so I can go to a 3D printing service or friend with a 3D printer and have new ones made
I am using a gaffa-based prototype now for about two years. It works and validated the use case but it breaks down regularly. A non-leaking version would be great :)
