DIY Pen Is More Fun to Make Than Use

Self-assembled and shrink-wrapped, the DIY pen is worth the work. Fraser Ross' DIY Pen is a flatpack biro kit. A laser-cut sheet of plywood contains pop-out wooden donuts of various sizes, and these are slotted to fix onto two spars which form the twin scaffold spines of the pen.
Once you have assembled this torpedo-shaped skeleton, you pop out the nib and clicky-button from the frame of the kit and push them into the ends. Finally, you slide a rubber sleeve over the whole thing and heat it with either a hairdryer or an oven.
