Graciously provided to me by Martin Bondéus , I colorized and properly aligned all the parts. This STEP file includes both the BondTech BMG-M and the Slice Engineering Mosquito Hotend.
The included STL is not meant for printing, while it could be printed, but is merely a requirement for posting on Thingiverse. The included STEP file is intended to be used as a placeholder, and for designing parts to be used in conjunction with the parts included in the STEP file.
I post source (STEP, .stp) files with each of my designs, so feel free to modify. If I forgot to post a source file, send me a message and I will post it. I also like it when others post their source files, it is fun to make things, and even more fun when you can customize and personalize them easily.
STEP source files (.stp) can easily be modified in many CAD packages like AutoDesk's FREE to use Fusion 360. You are free to modify and customize anything.
