These adjusters will help align the frame which will improve the levelness of the bed and resonance tuning if you have klipper setup. Install 3 at the bottom and 3 at the top, you'll need to remove the extruder. loosen all the bolts holding the sides on and then lightly snug them up. you want them to move when rotating the turnbuckles but not super loose. measure lower corner to upper corner in a X pattern on all 3 sides and rotate the turnbuckles either in or out till everything is pretty much even with each other, then tighten up the bolts holding the sides on, remeasure to make sure nothing moved and reinstall extruder. I printed these at a high layer height of .36 which made me have to do some sanding and filing to get them to fit and rotate well. you may want to print them at lower layer height to avoid post processing.

Print: 6 lefts, 6 rights and 6 turnbuckles. ( I shortened the turnbuckle in meshmixer because i didn't know of an easy way to do it in cad, also increased its size by 10% in superslicer/prusa slicer so it fit right/well. use the slicer to cut up the models and do your own test fit before "trusting" me, I'm a noob.) You'll need some Tnuts and some M4 bolts or whatever you have available I have included the step files.
