Legos or 3D printed harnesses for cable management?

Looking for feedback on some little tweaks for cable management. I’ve found that there are some really expensive versions of cable management out there for purchase, but the shoestring budget and my DIY personality have me looking at possibly creating some custom wiring harnesses using either LEGO Engineering sets or coming up with something in TinkerCAD to print on a 3D printer.

I’ve already been experimenting with custom camera mounts in 3D printed space for our IP cameras, but I’m curious to see if anyone thinks this would be perceived as “unprofessional” - No one is really going to be seeing these creations other than possible contractors in the future. Also, open to other ideas or sources for cost efficient, non-supply constrained, physical cable management. Thanks everyone!
