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.

ALL BATH INTERFEROMETER PRODUCTS HAVE BEEN MOVED TO MY NEW STORE HERE:

https://thegr5store.com/wp/Every laser comes with a calibration card telling you the wavelength (every laser is a little different - usually 650 to 660nm). Every laser runs on normal USB power (5v) which comes from phone chargers, USB cigarette adapters, USB batteries, computers, laptops, etc. Comes with 1 meter long power cord. You must supply your own USB power source.

This laser has 2 advantages over the cheaper laser I sell: larger beam and glass lens.

The glass lens means it is easy to clean without scratching. The other laser I sell has a plastic lens secured with a spring and the spring scratches the lens more and more every time you take it apart. This laser doesn't have any spring touching the lens.

Replaces Ultimaker2 teflon part. This is made of PTFE but it's a high temperature teflon. First there was regular PTFE (both Ultimaker and 3dsolex). Then there was "TFT" (3dsolex and soon after Ultimaker). Now there is "TFN". TFN lasts about the same amount of time as TFT depending on temperature. Learn More
