Bic Pen

You need to have an inside of a classic Bic pen, which can be easily removed after taking the lid off. The orange is the case, and blue the lid. They slot in together, and now you have your 3D printed pen! I printed both bits at 0.16mm layer height.

Orange:
I printed this one with a raft and no supports. A raft increased the surface area touching the buildplate so it will stick better and doesn't wobble the higher you go.

Blue:
I rotated this 180 degrees, and printed this with a raft and no supports. The clip is thin so slowing down the print around layer 193 until 261 is reccomended.
