Choice Chamber for Biology Experiments
Description
Our biology teacher showed me a vacuum molded choice chamber that they use with their students and asked if we could re-create something similar with our 3D printers. It features 5 total chambers (one in the center and four on the outside). The total dimensions is too large to print in one go on most 3D Printers, but with this modular design, you can print off the center and the outer pieces separately. The keys between the pieces have a 0.4 mm tolerance that should be enough for most printers. Design is minimally thick to speed up printing. Bottom layer is 0.8 mm (4x thick printed at 0.2 mm per layer) Original CAD file on Onshape is available [here](https://cad.onshape.com/documents/e74f7405932e113a18faf78e/w/88276c95addc537777477200/e/6a39a716e75a0a80b03d98cb?renderMode=0&uiState=661bf1830a26f573f1446d27).
