This is a Water Aspirator Pump based on the Venturi principle. It is designed to create a moderate vacuum for chemistry laboratory applications, such as vacuum filtration (Buchner funnels), rotary evaporation, or pulling gases through a…
A sturdy, reusable replacement cap for standard 1‑gallon water and milk jugs This model is a functional, easy‑to‑print cap designed around the 38DBJ neck standard , commonly used on 1‑gallon water and milk containers in the US. It’s a…
This is a 3D‑printed adapter that converts a 1/4 inch female flare connection to a 1/4 inch NPT male thread. I designed it to connect a vacuum gauge directly to a vacuum pump for quick testing and diagnostics. The geometry is optimized…
Arduino UNO R4 WiFi Spin Coater Controller + Custom 3D‑Printed Enclosure This project is a compact, purpose‑built spin‑coater designed primarily for coating 1/3‑size glass squares cut from standard microscope slides . It’s ideal for…
🧪 Ultrasonic Slide‑Cleaning Carousel (25 mm × 25 mm Slides) A solvent‑resistant 3D‑printed carousel for cleaning small microscope slides in an ultrasonic bath. Summary This project is a circular slide‑cleaning carousel designed to hold 25…
This enclosure is designed for the Arduino UNO R4 WiFi Thermal PID Controller , a fully web‑based temperature‑control system that drives a heater through an SSR and reads temperature from either a DS18B20 or a MAX31856 thermocouple…
This is a simple but very effective 3D‑printed jig designed to help you cut a standard 25×75 mm microscope slide into three equal sections. If you do any kind of spin‑coating, perovskite work, thin‑film testing, or general lab…
