pH Probe and Temperature Probe Holder

This is a holder for an [Atlas Scientific pH Probe](https://www.atlas-scientific.com/product_pages/probes/ph_probe.html?) ( or other appropriately sized probes) and a [Waterproof DS18B20 Temperature sensor](https://www.sparkfun.com/products/11050), which suctions to the side of an aquarium. Having these two sensors together allows for temperature compensated pH readings, giving you accurate results no matter the application. The black model was made with PLA. The clear was made with T-GLASE food-grade material.
