Multi-Type Graphite Holder/Organizer

I have a lot of graphite, and I decided to design a holder so it wasn't just scattered all over the place. I'm still working on it: currently, there's a V1 that has more or less random (base) sizing and a V2 with standardized base sizing, even if it's sometimes less efficient. I also plan on adding a V3 that has dovetail joints so that multiple organizers can be connected. Unfortunately, it was not practical/useful for me to make these models in the gridfinity layout. 

There shouldn't be any special printing requirements: I printed these without supports, in PLA, using the default Orcaslicer profile for the Elegoo Centauri Carbon. One thing that may be an issue is the small walls in some of the (mostly V1) designs, so make sure your printer can handle those. 

I've tested these holders to fit four general types of graphite holders: Ain Stein, the diamond-shaped Pentel Hi-poly, large rectanges, and small rectangles. 

The large rectangles are 20.3 by 9.5 mm, and in my experience they fit:

• Pentel Hi-poly (the big rectangle version)

• Pilot Neox

• Pentel Ain

• Uniball Smudge-proof

The small rectangles are 13 by 7.5 mm, and in my experience they fit:

• The small Uniball graphites that come with pencil packages

• A random Faber-Castell

If the provided models don't fit your graphite containers (or if you have any other suggestions), let me know and it should be easy to modify these to fit.
