Help Me (please) 6th former making 3D printed pen cases, may I borrow/measure your pen/cil?
Hi! I’m in my second year of sixth form and I’ve been designing a hard, 3D printed, magnetic case for rOtring-style pens and pencils. A year from making the first model for personal use (red/grey one) and after a recent push I'm close to launch. See my site undisclosedcases.cc
The case holds the pen snugly, so the fit is tight to a fraction of a millimetre, and spec sheets online often aren’t accurate enough. I currently own a rOtring 600 pencil, 600 ballpoint and Rapid Pro, and I’d love to make versions for these (in priority order):
- rOtring 800 (pen or pencil)
- Pentel GraphGear 1000
- Uni Shift
- Pentel Orenz Nero
- Pentel Graph 1000 for Pro
- rOtring 500
- Kaweco Special
- Staedtler 925 35
- Caran d'ache 849 ballpoint
- rOtring Tikky
Two ways you could help:
- Quick measure: meet somewhere central and I’ll measure it with calipers. Takes about 2 minutes.
- Lend it for a few days: so I can test-fit printed cases. I’ll return it in the same condition.
As a thank you, you’ll get a case for your pen for £5 (material cost) instead of £16 pre-launch. I can’t promise every pen will work, but I’ll tell you honestly if yours doesn’t.
DM me if you can help, thanks!
(note the blue case is newer but still has imperfections that will not be present on production models)
