BonePen – the bone-shaped ballpoint pen

The BonePen is a fun, easy-to-print ballpoint pen designed to look like a bone.

No supports are needed — just print, insert a standard ink refill, and start writing! Includes a protective cap for the tip.

Assembly:
Use a regular straight ballpoint refill (3 mm diameter). Cut it so that the inserted length is 95 mm, plus the extra length you want the tip to extend.

Perfect for makers, students, or anyone with a sense of humor — the BonePen turns writing into a skeletal experience! 💀✍️
