ACTUAL CAD IS KINDA HARD
That's one of several things I learned in the process of creating the MAKO. But before that, I think a brief backstory is in order.
So, for those of you that don't know, for the last nine months, I've been living in Troy, NY and studying Electrical Engineering at Rensselaer Polytechnic Institute (go Engineers!). If you don't know what RPI is, it's not important. The main thing is almost immediately after moving in last August, I joined the campus makerspace as a volunteer. The Forge is a really friggin cool place. Since I've been there, we've changed rooms and nearly tripled out number of machines, taking us into the territory of an actual makerspace, capable of serving the ~7,000 students who may choose to come to us. Anyway, during that expansion, we purchased a Markforged Onyx Pro, which I highly recommend you check out to get a full picture of because my description will never do it justice. Basically, the main nozzle (of the two) prints in Onyx (a custom blend of chopped carbon and nylon) and the secondary "fiber" nozzle prints, in the case of the Onyx Pro, fiberglass. Yep. Like actual friggin fiberglass. And the next model above this can do kevlar and carbon fiber threads as well as just plain ol' fiberglass. No sweat.
The moment I laid eyes on that gorgeous machine, I knew I was going to have to find an excuse to use it. So, I set about designing a frame that could essentially only be 3D printed, and would do best on this machine. After a few failed attempts, I succeeded, and this build is the result!

THE BUILD
The MAKO is by far the most unique build I've done, but also by far the cleanest, which is great because it was one of my main design foci. Cable management is very important with this build, so pay attention to the PDF on the Thingiverse page! I took this build nice and slow so I could properly document every step (within reason) and make a decent build guide. If you've done this sort of thing before, go for it, but I'd still recommend a quick glance at the pictures in the manual at least because this frame has a few quirks. But that's all I'll say about the build; I didn't write a 15 page PDF about it for nothing!

SINCE IT'S FREE...
...please consider donating the money you saved to Loggerhead Marinelife Center. They do seriously important and amazing work, and since you didn't have to pay for the frame, you might as well chuck a couple bucks to something that matters. The whole reason I named it the MAKO is because the shortfin mako, a species prevalent along Florida's Atlantic coast, is the fastest shark on record. Anyway, enough panhandling. Enjoy the build, or if nothing else, the pictures!
