I use caps and plugs enough to keep them in my cart but I can't stand things out of place so I made a holder for them. One set for JIC caps and another for my o-face set. Version 2 that I posted is a little taller to hold them better and fixed some little things. Would be best to print in PETG to hold up to oil that will leak out but I just used PLA and it has worked for the last two years.
V1 should fit most cap and plug brands.
V2 is for smaller caps.
I printed one of each to fit my two cap and plugs sets.
