Printing Tips

  • Always clean your build plate with water and mild soap.
  • No Supports - All parts are designed to print without supports.
  • Brim - A brim is required for the body of the pen.
  • Recommended Material - PLA Basic and PLA Matte filaments

Assembly

Remove the brim from the pen body and carefully deburr.
Use an ink refill that is longer than 92.8mm (3.65"). Shorter ink refills will require custom ink caps, such as the S-7S ink refill.
Insert the ink refill into the pen. It should be a light to moderate press fit. Do not remove once inserted.
Use a utility knife to score the perimeter of the ink refill flush to the rear of the pen body.
Snap the ink refill pointing away from your face and over a paper towel.
Slide the ink cap over the rear of the ink refill and into the rear of the pen body.
Firmly press the ink cap into place.
Snap the pen's cap into place and it is ready to use.
