Frame Braces for Creality CR-10, Tevo Tornado, and Afinibot A31

YO DAWG I HEARD YOU LIKE MY BRACES SO I MADE MY BRACES WITH LESS VOLUME SO IT WOULD BE QUICKER TO PRINT MY BRACES AND PIMP YO MACHINE!!! Here is a bracing system for the Creality CR-10, Tevo Tornado and Afinibot A31 3D printers. I took inspiration from the Wanhao i3 braces and directly used AzzA's ball design. All of the pieces fit within the 300x300x450 build volume of that printer. You lose approximately 12.5mm of vertical travel, but I feel the extra rigidity is worth the slight loss in Z travel. I have oriented the pieces for optimal printability and strength. I also added Fusion 360 and STEP source files because I'm cool like that. The Triangle brace and balls remain unchanged. I printed the frame brace pieces in PLA just fine. They don't require a lot of heat. I suggest 25%-50% infill. Print with the flat, outside surfaces on the build platform for the best strength in the direction forces are moving through the printer. For the new style, you'll need to use an M5 tap on the corners at the ends of the extrusion to install four bolts directly into the frame. Also, remove the "'T" piece - it's redundant with the tingle in place. I've added braces to four CR-10/Tornado machines and now have a lot of T brackets hanging around. BOM Print one of everything except for the balls. Print eight of those. Old Style 50 - 5mm T-slot nuts (you may not need them all, but get a 50-pack anyway) 50 - M5-0.80 x 12MM button head socket cap screws, allen head 50 - M5 washers 2 - 24" lengths of M8 or 5/16" threaded rod and eight matching nuts. I advise using washers between the balls and nuts - I'm using flanged nuts. New Style: 16 - 5mm T-slot nuts 16 - M5-0.80 x 12MM button head socket cap screws, allen head 4 - M5-0.80 x 12-20MM button head socket cap screws, allen head (for the tapped areas) 20 - M5 washers 2 - 24" lengths of M8 or 5/16" threaded rod and eight matching nuts. I also advise using washers between the balls and nuts. Edit 2-26-17: Removed Y motor mount - it doesn't seem to be any sturdier than the factory one. I'll design one that works with the factory one. Edit 12-3-17: Added STEP and F3D file formats so people can edit. Edit 3-4-18: I added quicker-to-print models for the top and bottom front braces, and added Tevo Tornado to the list. Edit 3-10-18: I noticed a few misplaced holes in the lower pieces - I corrected them. Deleted old balls and added faster/easier-to-print balls. Just use eight-millimeter nuts as you did before, but now you can access them with actual tools. I advise using washers between the nuts and the balls. I used flanged eight-millimeter nuts. Edit 4-7-18: Made a change to the "Triangle" piece to give more clearance to the bolts on the right side X gantry bracket. Tevo sticks those bolts out pretty far, and on my Tornado, the backs of the bolts rubbed. So I made it a chamfer instead of a fillet to increase the clearance.
