1. Testing Design rules
---
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.
How to evaluate the test geometries at: [link](http://wp.me/p22K2I-1TOt)
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.

Next after, watching some videos on making compliant mechanisms, I made a simple pick-and-place plier to test out the bending.
