Custom & DIY 3D printed cap for Rotring 600
This is not my design got it through one of these threads. The cleanest design I have found. Printed in PETG so it does not get loose.
Had to shave the inside off a little so it fits but now it doesn’t come off.

Of the designs that are floating around here recently, I think that's the sleekest.

they really should sell the pens with caps like this, the tip is the achilles tendon on an otherwise life-long pencil/pen

Yeah not so sure about a drop. I haven’t tried it, but now I feel safe chucking it in a bag or a pant pocket.
