# 3D Printable Cases for [DIY Frugal Arduino CO₂ Monitor](https://github.com/ericwooshem/DIY-Frugal-Arduino-CO2-Sensor) CC BY-NC-SA [Brian Woo-Shem](https://www.brianwooshem.com) & [Eric Woo-Shem](https://github.com/ericwooshem) These are cases for our [DIY Frugal Arduino CO₂ Monitor](https://github.com/ericwooshem/DIY-Frugal-Arduino-CO2-Sensor) project. See the full project instructions on [GitHub](https://github.com/ericwooshem/DIY-Frugal-Arduino-CO2-Sensor). # Files `DIY_C02_Monitor_Case_SIZE-PARAMETERS_v#` #### SIZE **Small**: 130x80x48mm. For our sensors, the main power battery is outside of the case. Tested and works. **Large**: 160x96x50mm. Designed for fully-contained sensors where all componenents including the battery fit inside the box. Not yet tested. #### PARAMETERS **Hole-** Has additional hole for running a USB cable into the box for power. Only really needed on the small boxes. **-ScreenSide**: Hole is on side where we put the screen **-SensorSide**: Hole is on the side where the sensor is mounted **NoScreen**: Removed hole for the screen. Useful if you choose not to have a screen, or want to operate in stealth mode. #### 'v#' Version number. Current version is v8 as of 2022-02-11. # Printing Recommended Settings: Worked for generic Prusa-type printer and Cura - Material: Generic PLA - Color: Does not matter, but we prefer if each pair of case and lid are the same color if possible. - Profile: Draft (Extra Fast would probably work too) - Infill: 10%, Grid - Support: Yes, density 10%, grid. Only needed for the one rectangular hole, so I used an overhang angle of 55 and - Minimum Support Area = 26mm^2 to avoid putting supports on the letters. - Adhesion: Skirt - To reduce the amount of filament use Wall Line Count = 2 and Top Layers and Bottom Layers = 3. If filament is not a concern, use the defaults in Cura. # Credits The main CAD is forked from: ["Parts Box With Notched Lid"](https://www.thingiverse.com/thing:812074) by [theronin](https://www.thingiverse.com/theronin), licensed under the Creative Commons - Attribution - Share Alike license.
