Race nozzles heat filament much more thoroughly than regular matchless nozzles due to their internal structure. Allows you to print at lower temperatures or faster. Compatible with 1.75mm Olsson block, 1.75mm block v3, printrbot UBIS 13S, Raise3D or other e3dv6 nozzles.

For 1.75mm filament (not 3mm filament).

If you use this nozzle on an ultimaker you must have a 1.75mm filament Olsson block or block v3 (a conversion kit).

Works also with Raise 3D N2 printers. Learn More

Convert to 1.75mm! This is experimental. I haven't tried it - I don't know if anyone has. I'm not sure if changing this part alone is enough - it seems like it should be as on the UM2 you only have to change the heating block and the teflon part - certainly you don't need to change the bowden. So I think it will work.

Replaces Ultimaker Original (not Ultimaker2) teflon part but this part can print at 255C continuous for years. Never replace your teflon part again. This is made of teflon but it's a high temperature teflon. Learn More

This contains parts you need to do the Mark 2 dual head upgrade (except the head fans). Details on the Mark2 are here:

https://magnetic-tool-changer.com/

The above website has the complete bom (on github) and detailed instructions. Everything in the photo is included. I purchased this part from this link here:
https://www.aliexpress.com/item/Mark-2-board-hotend-extruder-kit-for-Ultimaker-2-3d-printer-dual-extrusion-full-kit/32829918859.html

I gave this kit to 2 people to try out and they both said the same thing. Everything worked perfectly except the print head fans. You will need to get the 2 print head cooling fans (not the 3rd head cooling fan - just the side 2 fans) yourself. I also tested the fans myself and indeed they do not work. So I recommend you get the part number off your existing fans and order 2 of them through digikey. Or possibly fbrc8.com if you want them with the connectors already mounted.
