Big Tree Tech ZSYong Mix 2 in 1 hotend

Hello Guys, 

I want to share with you all my big tree tech hotend adapter for ender 3.

I have converted my ender 3 to dual extruder and some one wants to do the same,  I will save you the trouble of designing this part.

You will need screws:

M3x5 2pcs
M3x20 4pcs

The screws I have for the 3010 fan i forgot if they were included with the hotend when I got them but if you have your own

M3x15/20 4pcs

Supports are not needed in both prints if the orientation is correct.
