Many of us, myself included, love the smooth lines of Bic pens for drawing, but find them uncomfortable to hold for extended periods. My solution to this common problem is a simple, 3D-printable Bic pen grip spacer.

This spacer slides easily onto the pen and fits snugly behind the ring where the tip connects to the body, providing a more comfortable grip.

You can print it in PLA, but for an even softer, more ergonomic feel, try using TPU filament. The best part? This spacer is reusable and compatible with any pen that has an 8.33mm diameter.
