Here's a cool 3D printing project. In this instructables, I'll show you how I made an awesome puzzle pen using 3D printing.

3D Printer: Dremel

Filament: PLA

Modeling Application: 123D Design Desktop ( get from: http://www.123dapp.com/design )

Step 1: Draft the Design

Draw out the draft design and puzzle pieces.

Step 2: Modeling

Modeling the pieces in 123D Design Desktop following you design draft.

Note: You must design the teeth using same dimension. And test the clearance, 0.1mm maybe so tight, it is so hard to pull out the pieces for me. So, I used 0.2mm clearance, it is easy to pull out.

Step 3: Print Out

Print them out. According to the length of the cartridge, print body pieces repeatedly. You also can print with different colors.

Step 4: Assembling

Complete the puzzle by assembling all the pieces.
