this will allow you to mount the BLtouch on the side of the Heat Sink of a Chimera/Cyclops Style Hotend

This works well with the Stock Tevo Hotend and will bolt up on the side

I made this one to help me get the offset for the Volcano hotend but should work with the normal nozzles also mounted higher on the heatsink

Yes

ABS or PETG something with a high melt point seeing as this is in close proximity to the hotend
