think&have multicolor blending hotend

thingiverse

I will make your product work with 2-4 filaments of 1.75mm size using a standard M6 nozzle that's perfect for Bowden extruders only. You'll need a standard 50 mm fixation and a fan to run this hotend efficiently. A small milling machine or lathe is necessary for creating machined aluminum parts that meet your specifications. I've included OpenScad descriptions of the parts, but you shouldn't try to print them with ABS plastic as it's not recommended. This product lets you turn your single-filament 3D printer into a multi-color machine if that's what you want. Working with one nozzle for multi-color printing has some benefits and drawbacks compared to using two hotends. To learn more, check out the attached PDF document that I've provided in English language this time. Since October 2014, my project is up on Facebook under 'Think and Have' so feel free to see the product development and manufacturing process unfold there. Here are some updates: On February 1st, 2015: I modified the heating block for a smaller volume which gives you better results with color changes since it reduces unwanted mixing issues. As of May 23rd, 2016: I added the Heater part to 'Sixpack' model which works great for six mixed filaments and six extruders in total. You'll also see some updated description of this product within the attached PDF file now.
