SKR 1.3 - Ender 3 Rear Case

prusaprinters

I wanted a custom case with adequate airflow for my SKR1.3 board on my ender 3. I loosely based some ideas off of other people's design, but I wanted my own setup for my own needs, primarily having the inlet fan have 5 channels to put air past all 5 stepper drivers. M3 Threads are built into the model. Recommended sizes are M3x4mm. Also, most walls were built to be 1.2mm thick. The case and the lid will be pretty flexible, but it allows it to keep material cost down. Total material cost is approximately 350 grams. I've also included some chain links if you want to run chain links on you're stuff. Print Settings Printer Brand: Creality Printer: Ender 3 Rafts: No Supports: Yes Resolution: 0.2 Infill: 25% Filament: Polymaker Polyflex PETG Black Notes: The inner duct will want supports on the interior, but they really aren't needed. Only the 3 mounting posts need support on that piece. The fan\_inlet will also need support for the mounting wings. Other than that, you should be able to get away with no support on the lid and case. Category: 3D Printer Parts
