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.

Snap the pen's cap into place and it is ready to use.

Thank you so much for the support =)

@inakarmacoma

in case anyone is curious to compare the dimensions of the pocket size and telescope size of this model, a pilot G2 is approximately 142mm or 5.6" in.

Prints and works like a charm Wouldnt recommend PLA matte though, too much stringing

I was looking for a pen that I could always have on me at work, and this model came to the rescue and I've been using it ever since (even printed one for my boss!), thanks for you for the instructions and attention to detail and for sharing it with us!

Excellent little pen pocket handy 👌

@reeksypie

Few wraps of thread tape to take up the slack. Now it feels a bit more secure. Printed in PLA Matte

@stae_one

Excellent design

Much more compact 👍 I had printed another version with small circular openings that was stylish, but it ended up breaking in my work environment
