Wanhao i3 v2 Rear Z-Brace

thingiverse

These are the printable parts for a rear z-brace for the Wanhao i3. I made it for my Monoprice Maker Select V2. I wanted them in the back so that I still had clear access to everything from the front of my machine. It's designed to fit 5/16 threaded rod (allthread) that can commonly be found in hardware stores in the USA. I left large flat spots for washers. You'll need 2 x 17" minumum lengths of 5/16 threaded rod. I used 18" since that's half of the 36" rods my hardware store carried. You'll need 8 x 5/16 nuts and 8 x 5/16 washers to secure the rods. To attach the mounting brackets to your machine, you'll need 10 x M3-0.50 bolts about 8mm or longer (might be able to use 7mm). I used 10mm long to be sure there would be a little extra room if I had to rework the bracket designs or add a nut and it's no problem that a little bit of the bolt sticks through. Finally, the cable guide that connects the base of the machine to your X gantry would bump into the z-brace rod on that side, so I also included a little wedge shape that you can use to angle that cable guide inward to avoid the z-brace. You'll need a couple more M3-0.50 bolts for this, since the stock two may not be long enough.
