<h2><b>2021-04-26 update</b></h2> Let me say that few months later these parts looks rock solid and did not need any adjustment, but design not as good..... I took some time to review all parts hoping they will result as strong as before. now there are 3 t-nut bots on botton arm and up to 5 available on top one. I also change some print parameters as shown below Shown printing position should result in the best time/quality <h2><b>2020-12-16 update</b></h2> After first installation I realize that even with high infill the upper part is too flexible. Made some adjustment, printed and after installation they looks much bigger but very strong. added also another hole for an extra screw if needed. <h2><b>2020-11-22 update</b></h2> There are many accessory like this, but some seems interfere with X assembly at maximum height, some other for me just looks bad. Covid give lot of time for browsing web, looking for parts and I tried a different solution. The idea was to not touch any printer part or accessory and allow anyone to install it, so for example, you can install with power supply in original position or rear horizontal Also the upper support can be installed with the optional bearing for Z-axis. Parts were drawn to tight fit original frame so any small difference in aluminium shape can create problem. as written below I made a mistake while ordering carbon fiber tube, 7mm outside diameter is not enough, should be better an 8 or 9 mm (10 is ok) this will not require to print the "threaded end" STL here attached there are only left supports, for right just mirror them in CURA. IMPORTANT buy left and right "Rod end joint" this allow to push or pull just rotating the rod. this is the BOM I bought these 6 mm (2 Left and 2 right thread) https://www.aliexpress.com/item/4000412352481.html?spm=a2g0s.9042311.0.0.27424c4dr3yflB then 2 of 7x5x500 mm carbon tube (7x5 are too small should be better an 8x5 or bigger outer size https://www.aliexpress.com/item/32798468986.html?spm=a2g0s.9042311.0.0.27424c4dr3yflB of course 2 M6 thread tap tool, one left and one right https://www.aliexpress.com/item/32732426960.html?spm=a2g0s.9042311.0.0.27424c4dFzoqfy 10x M4x10 mm screw and Tnut 4x M6x25 mm screw and 4 M6 bolts 6x M4x10 mm screw and Tnut ( optional )
