3Doodler may have only been looking for $30k in crowdfunding for their second-gen 3D art pen, but with ten times that amount raised in a matter of hours the stakes are high. Completely redesigned from top to tip, the body frame is thinner, quieter, and most importantly easier to handle. The new JetPack accessory is a portable battery power pack that follows you so you’re not forced to hug a wall anymore. Question is, has 3Doodler done enough to warrant an upgrade? I went hands-on to find out.
