Description

Note: I am still figuring out the best settings for most people. Since they are print in place, they are not smooth on the back, but there is no glue or assembly required. There is a little trade off in quality for convenience. 

 

I would love to hear any feedback. If these seem to work for some people, I hope to make some more in the future. 

 

Discbound / Mushroom Hole Notebook System

 

This was made to work with discbound or mushroom hole punched paper, such as the Happy Planner, Arc, Tul, or Jane’s Agenda planners. It allows for easy customization for a notebook. If you are unfamiliar with the discbound system here are a couple of quick videos on them. I'm not affiliated with them.

There are profiles for each size. Due to the size of the cut out, they start a 1 in(25.4 mm). All profiles include a single disc with brims and a set without brims. The ones without brims are made for plate with good adhesion such as cold plates that don't require them. I have test printed all of mine on a cold plate and have had no adhesion issues. The plates with brims is for plates with less adhesion to ensure they stick to the plate. 

 

These are print in place with a custom support, all that you need to do is just push the support off from the top and it should pop off easily. While you do lose some print quality on the back, it should not interfere with turning the pages. All the other models I found either print in two pieces, which I personally wasn't a fan of, or use general supports that were sometime difficult to remove. 

 

This is just the disc, other discbound accessories are linked below.
