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.

The composition book pattern is in the print profile 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 disc is technically not needed but I think it adds stability and you can replace the star “hole” with any decorative pattern for more customization!

I highly recommend printing the discs on a smooth build plate, since the texture can make the pages not turn as smoothly. It will take some force to get the discs into the rings, but printing them in two parts avoids the issue of needing supports and having a rough surface on the supported face.

UPDATE: I have confirmed these refills fit perfectly (amazon link, non affiliate): https://a.co/d/5pPSV12
