Air 2 - Lowered & Flipped Z Motors
by wasta, published
The download includes a right and left motor bracket, a dxf with additional holes/cuts for mounting/cable management, and an optional end-stop holder for the Z axis.
If you already have an Air 2 frame laser cut, you can use the printed bracket as a template to drill the 2 additional holes needed to attach the part.
This part is admittedly overbuilt, but it prints well.
**Edited: Added a Slim, Short, and Low-Poly Versions of the part.**
I have not printed or tested the short or slim versions, but they should work fine.
The "short" version of the bracket should probably only be used if the z smooth rod is cut long enough to reach the bottom smooth rod clamp. I worry it may not stay square otherwise?
Some kind of paper drilling template may also be needed for the "short" version if it is being added to an existing Air 2 frame.

Okay, I am going to try this one last time, but Wasta, is there a way of printing the left and right brackets apart from eachother? I am usually home late and don't have time to print a full board, but if I can print them one at a time I might just be able to print one a day :)
Do you think printing it in Aluminum would gain me accuracy?
I have found that buying a Prusa i3 frame in Alu is even cheaper and I hear it gains good accuracy.
I am noticing my Acrylic frame isn't as study as I would like it to be, even with all the added supports. Even after glueing the frameparts together in an absolute square configuration.
The .dxf included in the downloads is the Air 2 dxf with the two extra holes required to mount the lower z motor bracket. If you print it out on paper at 1:1 scale and lay it on your existing frame, it will ensure the centers of the holes to mount the lower z motor brackets are in the correct spot.
If you can find a 4mm drill bit for acrylic you will probably get a better result. I would also recommend putting a waste board behind the acrylic when drilling the holes so the bit doesn't break through the backside of the hole.
