Yes, I'll make more updates and add-on accessories to this design. Please feel free to comment on what you would like to see with this.

The pictures shown is the first section I've built and me testing it with a few full boxes of filament. (No issues holding that up)
I left the corner locks long so you can see where they go. Yes, they are a tight fit.

The concept is very similar to the wire racking you get at the hardware store.
You have uprights with little grooves in them, a lock that goes into the groove and a sleeve that goes over it to lock it in place at a certain height.

Since it would be difficult to print wire racking, I broke this down into smaller trusses that interlock to form a shelf.

To start, you will need to print the following.
4 uprights - about an hour each.
4 locking rings - Couple minutes
4 corner pieces - about an hour each
2 main trusses - about an hour each
