Pillar Braces for Rostock Max v2

prusaprinters

<p>The melamine frame pieces on my Rostock Max v2 have developed some play over time from printing at high speeds (80-120mm/s) and so I designed and printed braces for the base and top of the towers. The whole frame is very satisfyingly rigid now <img src="https://forum.seemecnc.com/forum/images/smilies/icon_e_biggrin.gif" alt=":D"></p><p>Of course holes have to be drilled in the melamine and the drop-in t-slot nuts can be quite frustrating, especially in the top. I used the largest hex wrench that would fit in the track to lift the t-slot nut into place for the top brackets. If you like to have a beer while you work, wait till you get the top bracket t-nuts in place. You'll need all your dexterity and by the time you finish you'll really need some suds. <img src="https://forum.seemecnc.com/forum/images/smilies/icon_lol.gif" alt=":lol:">&nbsp;<br>The top bracket has a void for the uppermost 1/4"-20 machine screw so don't remove that one. The lower one will need to be replaced with one 1/4" longer. I used M3 for everything else cuz that's what I already have. If you want a stouter screw you'll have to drill out the screw holes in the braces accordingly. Also, I used fender washers where they would fit. Because the upper brackets require removing existing hardware I only did one bracket at a time to reduce the chance of messing up the frame geometry.<br>In the pics I posted you can see wires poking out the corner of the lower braces. I had wires for LEDs running up through the extrusion track so I added a hole in the braces for that. Use it if you like or just ignore it.<br>&nbsp;</p><p>Print 3 of each as is and three more of each mirrored.</p><p>Model orientation for slicing should be on the triangular side (the side facing toward the center of the bed in the pictures) for best strength.&nbsp;</p><p>Print Settings:<br>ProtoPasta Original CF-PLA with a .6 nozzle. .35 layer height, 6 top/bottom layers and perimeters and 30% infill.</p><p>These things are basically solid and very stiff! I have had zero creep issues with ProtoPasta's CF-PLA on these. If you enclose your printer you should use something else though.</p><p>(These were previously posted on seemecnc forum and on thingiverse.
