Description
I wanted to test cooling fan performance objectively back to back, so I designed this part to help. Previously I had noticed the AIO micro 3D printer test did a good job of showing up the flaws of a lack of cooling fan, so I modelled a similar design. The main body is lifted up off the bed to allow a wide and difficult bridge. There are four gradually tilted arcs, from vertical to 80 degrees, pointing up, down, left and right. The reason to see if a fan that only blows from one side is at a disadvantage. The final feature is a central spire that is raised above the rest. Version 2b was my final design, I recommend only printing this one. The others are included for completeness. This process is covered in detail in this video: https://youtu.be/xmZCwJDyxYU Print Settings Printer Brand: Creality Printer: Ender 3 Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 10 Filament: X3D PLA Post-Printing ============= Inspect! Check the underside of the bridge, the underside of each arc, and the accuracy of the central spire. How I Designed This =================== Category: 3D Printing Tests
AI Analysis: This object is a mechanical part designed for a cooling fan, specifically a component that serves as a test fixture for evaluating the fan's performance. It features a blue plastic structure with a rectangular base and curved arms, intended to simulate the airflow path and test the fan's ability to handle various conditions. The part is labeled as 'Standard Ender 3' and 'Bullseye Ender 3' indicating its compatibility with specific printers.
