2 x Upper rod end
2 x Rod end

Non printed parts list

Threaded rods: 2 x M6x430mm. Can be longer but shorter will make the angles smaller and support not so rigid.

Nuts: 8 x M6; 4 X M5
Bolts: 4 x M5x25mm

Functional description

I wanted to make my printer frame more rigid. So I mounted it to am MDF plate that I had and printed a bracket. But it looked wery weak after printing and I decided to make something stable. Found those threaded rods I had from before and desighed this using them as main piece for adjustment and stability.

Printing tips

Since those are structural parts print slower for beter filament adhesion. Should be printed in the orientations showed in the screenshot so the forces will be along the strands. Supports are needed only on those parts shown on the screenshot.

Installation and adjustment

1) Install everything as shown in the photo. Dont tighten the nuts.
2) Tighten the upper nuts at lower rod ends to fix the screws
3) Adjust the frame to be perpendicular to the mount plate by tightening/loosening the top nuts at Upper rod ends.
4) Tighten counter nuts and transverse M5 bolts/nuts to fix everything.

Material: used PLA(blue) but after some time Upper rod end delaminated so I redesigned it and reprinted in PETG(black).
