APFSDS Pen

This custom pen design is inspired by the DM33 APFSDS tank round, which stands for armour-piercing, fin-stabilised, discarding sabot.It features a unique lid shaped like a sabot that clicks satisfyingly into place. Designed to fit the Gel Ink Ballpoint Pen Refill from Muji. Other refills won’t fit, so be sure to grab that one for successful assembly.It comes with 3 bottom pieces: 4 fin, 5 fin, or 6 fin. Only 1 of these is needed, so pick whichever you like most. Printing in clear filaments is recommended, as you get the bonus of viewing the remaining ink inside the cartridge. Heads up: people will mistake it for a rocket, but you and I know that it's not. Otherwise, a great conversation starter!
