Tolerant Press Fitting Circles

Building stuff to assemble and manufacture? You're likely to want to make bits that can slot nicely into each other and aren't horribly askew, so you want to know how your printer performs relative to whatever you're designing - and then you can work out a fudge factor elsewhere.

#### What's in the box?

Three parts consisting of a set of discs that are related to each other by simple multiples

- A: 12mm thick, OD of 36, ID of 24 and 6
- B: 6mm thick, OD of 48, ID of 24
- C: 12mm thick, OD of 24 and 6

In a theoretical world there's no gaps and so these would fit perfectly. Ha! In the real world, we have tolerance and manufacturing issues, which is really half the fun, right?

#### What goes where?

- C fits into B
- A fits into B
- C fits into A, both ways
- You can get two 12mm layers (theoretically); or
- A 6/12/6 stack; or
- A 12/6/12 stack



#### Things to consider

1. There should be no orientation requirement - if you have circular circles. If yo
