Frame Stiffener

thingiverse

A top frame stiffener with 10mm alignment tooling. Decided to try & stiffen the acrylic frame on my i3 Pro B's. This does actually make the frame stiffer, but I had to make sure that printing height was not affected. It mainly reduces X axis frame wobble. Measure from top corner of tooling to a fixed point on the frame, drill hole 7 repeat from the same position on the opposite side. I used M10 rods from an old stripped down i3 Pro B & cut to 325mm. The braces on the photo were measured at 25mm from the corner & I would not recommend less than that as the support discs would interfere with the wiring holes.
