Anet A8 Y-axis frame support brace

thingiverse

Here is yet another Y-axis frame support for Anet A8. Rather than using a large 3D-printed geometric bracket anchored to the primary threaded rods to stiffen the acrylic plate, this one uses new threaded rods near the Y-axis belt. Print 4 of these brackets, 2 for the front of the printer and 2 for the back of the printer. Cut 2 lengths of threaded rod and add 2 nuts and washers to each threaded rod. I used 3/8" diameter threaded rod, but any diameter with enough stiffness will do. The rod diameter in the OpenSCAD file can be changed to accommodate a different diameter. The lengths of the rod do not have to be very precise, since the depth of the brackets allows for variation. The rod should intrude into the bracket by at least a few millimeters, for stability, and should not be so long as to scrape the acrylic printer frame. I used lengths of 13cm (back section) and 21cm (front section). The front and back rods are not connected to each other in any way, but they should be aligned as closely as possible. The braces and rods drop into place with the nuts loosened, then the nuts should be adjusted to thrust tightly against the frame, but not so much as to add any stress.
