In the world of Stargate, we are taught that replicators are extremely dangerous. One, alone, can not do much of anything. But, when they combine, they can become dangerous!

Hopefully, four replicator blocks, combined into a pen, will not prove to be too much of a problem.

I made the STL for this pen over a year ago, and use the original print almost every day at work…but just realized that I never uploaded it.

(Quality in the pics is due to different printers. With the pen core installed was from an Ender 3 S1, while without is from Bambu P1S.)

Settings:

Layer thickness: 0.2 (or, better yet, variable layer height)

Supports: yes (basic grid (minimal))

Infil: 15% (any pattern you like)

Material: any

BOM: 1 ea Ballpoint Pen core. (Pentel R.S.V.P. Ballpoint Pen works fine in it).
