Correction: I misspoke the PolySupport is made by Polymakr
Dr. D-Flo upgrades his Maker Gear M2 with a Dual V4 Extruder. He uses this upgrade to print parts in two colors, parts with a easy-to-remove support known as PolySupport and a circuit board. This video will also serve as a quick tutorial for creating dual extruded parts. Unfortunately, the conductive Electrifi filament did not work.

Looking for a unique and classy technology-related gift for someone special? In the following videos Dr. D-Flo and his team launch a competition to see who can make the cheapest and classiest design for a Nixie Tube Clock. In this three-part series, the team describes their competition by laying out the rules (one of which is a $50 spending limit), combs through antique stores to find unique items, and then proceeds to design and engineer casings for these Nixie Tube Clocks. We hope you enjoy watching the competition and it gives you some great ideas for DIY gifts! Let us know in the comments who you think won!
