I designed this from scratch but it's largely inspired by Tech2c's pen holder found here: https://www.thingiverse.com/thing:2459624 Features showcased in Thomas Salanderer's video "Making PCBs the RepRap way!": https://www.youtube.com/watch?v=sL0LZFcNaow Parts required: * 1x Mount for Prusa i3 MK2 https://www.thingiverse.com/thing:3166868 * 2x LM8UU 8mm Linear ball bearings 8x15x24mm * 2x 100mm x 8mm Stainless Steel Round Bar * 1x elastic band - Hook this around the tab at the bottom and the pen carriage so you have gentle downforce on the pen. See the youtube video above for more. There are three pen holders: * 11.4mm maximum pen diameter - [Green] - This will fit many fine/superfine pens. * 15.8mm max diameter (Large) - [Light Blue] * 19mm max diameter (X-Large) - [Pink] this will fit the Staedtler 352 - 2mm tip. Some diameters of pens I have are: * Staedtler lumocolor fine & ultra fine pens are 9.5mm diameter. * Sharpie ultra fine is 11mm. * Sharpie fine/ultra fine cd/dvd marker (double ended marker) 12.3mm diameter * Staedtler lumocolor 352 2mm pen - 17mm diameter
