5U Vertical Post for Cage Nut mount

I have a set of the original brass insert legs to build, but when I initially started collecting the essential items I messed up my order for the brass inserts; ordering 8mm length instead of the BOM identified 4mm. Shipping from overseas in the US of A has become a nightmare again by my empirical evidence- sourcing USA-ish from Amazon I was able to find some 5mm length inserts, nothing shorter and not many. So I fired up Fusion360 and made these to use fewer inserts; I find the cage nuts install quite quickly. I’m not certain how much load these will manage- will update after I finish my LabRax build#1.I printed mine in Black ABS-CF with a .6mm nozzle on a X1C. I added mouse ear brims on the ends and fuzzy skin- not certain how much they help, but adding those two setting plus rotating the Verticals to align with the Y print axis and sequential printing resolved a serious warp I experienced on my first print; one or some combo of the four changes makes for a strong straight beam.
