Refillable Disc System Notebook (Discbound/Circa/TUL/Arc Junior 8 discs)

A fully printable refillable disc notebook! Compatible with half letter, junior, or A5 refill paper (common size refills for 8 disc planners like TUL, Circa, Arc, or other Discbound systems). I used a Happy Planner hole punch to create my own inserts but you can also find them online or in office stores. The discs are smaller than most of the ones you can buy, best for about 50-70 pages depending on the thickness of the paper. Leave a comment if you'd like larger ones, I can modify the source file. The covers and discs should be compatible with manufactured disc style notebooks, so feel free to print just the covers or just the discs if you are adding customization to an existing system.

I have included the composition book style covers and a blank so you can customize to any design of your choice. I designed the discs to have a separate outer ring and inside flat disc - the inner flat disc is technically not needed but I think it adds stability and you can put a hole in them with any decorative pattern for more customization!

RECOMMENDED PRINT SETTINGS:

For the covers, use a layer height of 0.16mm. For the composition style, change from black to white after the 3rd layer. If you are adding a custom design, try to make it 3-4 layers thick. Hilbert curve on the top layer will add a nice effect and make it look less "printed."
