UM2 hotend 9.4mm & 8.4mm adjustable spacer

[neotko 1,417]

It's untested because I have a long weekend ahead. But it should just work. It has two positions 8.4mm distance and the other 9.4mm distance. I printed it on PLA-tec. Also on 9.4mm distance you can see through if the Bowden it's on.

Printed on black PLA-tec (110-120 heat resistant) using window cleaner + 1 hairspray puff before heating the bed for adhesion. 0.1 layers 50mm/s fans full at layer 30ish.

Btw @anders-olsson uploaded his adjustable spacer (the one I use) and it rocks, so forget about my design and get his!

Could you explain the reason for the adjustability? I thought the spacer didn't need more than 1 length

If you use the i2k 1mm you need a different spacer if you want to keep the nozzle on the same height/not touching the metalfancap.

Also if you play with the coupler or want to use two different heights (dual?) without using a spring, then this helps (not my design but the one from anders).
