About this model

Same files as the original (great thing BTW) but I've enhanced the "kinematic arm pen" STEP file. In the original the diameter of the pen was larger than the size of the link. That required either a lot of support material or a non flat print. I shrank the diameter of the "pen" so that it is smaller. Now the part can lie flat on the printer bed. You will need some support under the pen shaft, but that doesn't hurt. The overall function of the thing is not changed - it still amazes people.
