This week I made some 3d printed tools and 3d scanned using photogrammetry.

I used [these files on thingiverse](https://www.thingiverse.com/thing:533472) to test design rules of the Ultimaker 3 I used in the lab.
These test geometries are designed to evaluate specific performance characteristics and motion systems in common low-cost FDM/FFF machines. Make Magazine's third annual 3D Printing Shootout was conducted using these files, created by Andreas Bastian to benchmark performance of desktop 3D printers.

There are 7 individual files that help test:
1. Dimensional Accuracy
2. Bridging Performance
3. Overhang Performance
4. Negative Space Tolerance
5. Fine Positive Features Performance
6. XY Resonance
7. Z Resonance

I will finish this part when I am back in the lab.
I wanted to make simple tools this weeks, so I experimented with simple joint mechanisms. Some references that I used to develop my designs:

I first made a scaled-up version of a simple Gemclip and some other simple geometry clips. I bent one end to add a dimension, that does not allow it to be made using only one subtractive method.
