Lewihe Play hotend fan support (AKA happy boy)

thingiverse

I'm wrapping up my Lewihe Play 3D project, and I've completed all the parts I wanted to include. However, changing the hotend fan support proved to be a real challenge - it's a nightmare if you don't want to take apart the entire coreXY system. I had to make some changes and test them out, but those pesky M4 nuts kept falling off. So, I came up with a design that embeds the nuts, allowing me to assemble the printer without worrying about losing them in the process. This solution definitely worked its magic. Huge thanks to Lewihe for inspiring us all - this printer project has been one of the most exciting things I've ever built. The Lewihe Play 3D is a real marvel in its class, and I'm grateful for their innovative idea. Keep up the fantastic work, guys! This design pairs well with another creation: http://www.thingiverse.com/thing:1527259
