TwoPlus - Modular addon for Multi-color extruding

thingiverse

TwoPlus allows you to print with three 1.75mm diameter filaments using a single nozzle. There are more add-ons of this type, but I couldn't find one that allowed me to print with three filaments at once, so I decided to design it myself. It's modular because it allows you to adapt to any type of printer: Prusa, Sparkcube, etc. I will be uploading the different modules as I design them. UPDATE (October 16, 2016): - Chinese JHead Adapter Module (http://www.thingiverse.com/thing:1830945) I have also added a tool to cut the filament comfortably, but be careful, it's not safe and I disclaim all responsibility for any cuts, amputations, medical bills, or other possible accidents with the cutting blade or cutter itself. ColorMixer is in alpha phase, so I don't recommend wasting filament until it's finished. It's designed to use the typical pneumatic connectors of Chinese hotends, which have an approximate diameter of 9.5mm on the crest of the gas thread. As I mentioned earlier, ColorMixer is in alpha phase, feel free to ask for specific measurements if you need to modify diameters. Post-Printing Use of the tool for cutting the PTFE tube I recommend drilling (manually) every passage of the Teflon tube to 4mm. Everything is designed without curves so it won't get damaged when passing with a drill bit. The tool should be supported on a secure table (that doesn't move) or a surface with a right angle (90 degrees). I usually use the blade without the cutter handle in my work and consider myself quite skilled. I use it like that because it allows me more touch and precision. The Teflon tube (PTFE) is soft, go slow and pass through the different crests so everything settles correctly. It's ideal for the cut to follow the plane of the tool on each cut to avoid any possible holes (which I don't think are critical, to be honest).
