A custom shell for your ballpoint pens! Prints in 10 pieces:

8 Shell pieces (for build plate texture transfer)

2 casings for the ink. 

NOTE: It fits most replaceable ballpoint ink tubes in the ~4mm hole. The accuracy of the hole depends on your printer! Also, note that you may need to clip those small “nubs” on your replacement ink tubes to ensure proper fitting. The pen was designed for a tight and secure fit. [Glue in assembly is required]

Tip: For the best texture transfer from your build plate to the print, ensure first layer temperature is 240 (up 20 from PLA) and slowed down.
