It appears you've shared two Amazon product listings along with a detailed description of a 3D printing project you undertook, specifically designing an aquarium controller box. This box seems to be designed to control various functions in your aquarium using a Raspberry Pi or Arduino, and it can also work manually through switches. The design incorporates common US Decora-style outlets and features cable glands for power cords and switching wiring. Here are some key points from the description: 1. **Project Overview**: You've designed an aquarium controller box that can be controlled by a Raspberry Pi, Arduino, or manual switches. It has a hinge opening feature to allow easy access inside. 2. **Design Features**: - The box is made of 3D printed parts with a thickness of .24mm. - It features common US Decora-style outlets and cable glands for power and switching wiring. - The design allows for the use of relays, with a blank mounting plate provided that can be customized with standoffs to fit specific relay types. 3. **Printing Details**: - You printed it on an Ender 3 using a .24mm thickness layer and a 5mm brim for stability. - The infill is at 20% density due to the desire for durability against cord insertion/removal forces. - It was printed without supports, relying on the design's contours not to require them. 4. **Assembly Details**: - You used #6-3/8" pan head Phillips screws for attaching relays and the relay mounting plate. - #6-5/8" pan head Phillips screws were used for attaching the top to the bottom of the box. 5. **Updates**: - There have been two updates to the design, including enlarging screw holes slightly in the base and relay mount plate to reduce the risk of breaking standoffs, and adding clearance to cable gland holes and nuts. This project showcases a thoughtful approach to designing a functional and durable enclosure for an aquarium controller.
