Ender 3 Pro AEIOU - Electronics enclosure

thingiverse

This was designed specifically for the Meanwell PSU from the Ender 3 Pro. If you've ever fantasized about having a CR-10 instead of an Ender 3, now's your chance. Put your Ender in an enclosure and need somewhere to stash all those electric components? Enjoy pushing yourself and your printer to the limit? Then you're at the right place! You can now have all electronics packed into one convenient unit. I spent weeks searching for a perfect electronics enclosure that could hold everything I needed - an SKR Mini E3/Melzi, a Raspberry Pi, and some relays. Nothing seemed quite right until I finally created this design using Fusion 360. Make no mistake, this is my first attempt at designing something like this, and it's far from perfect. Print this at your own risk as I disclaim any responsibility for damage to your printer or your mental well-being. This enclosure was designed with the Meanwell PSU from the Ender 3 Pro in mind. Get down to business. This design is centered around the following components: Relay module: https://www.amazon.com/gp/product/B072TR82K9 MOSFET module: https://www.amazon.com/gp/product/B077SBC1B5 CSI to HDMI adapter: https://www.amazon.com/gp/product/B06XDNBM63 Buck Convertors: Your favorite cheap blue buck converters Secondary AC input: Any fused AC input, such as https://www.amazon.com/gp/product/B01GBW8J8A Fan: Your favorite 6025 fan or anything thinner Hardware required: Outside: 4 - M3x8 case screws 2 - M5x8 display screws (Reuse from original display) 4 - M5 fan screws (No length requirement, or use fan screws) Top Level: 4 - M2.5x5 buck converter screws 6 - M3x5 MOSFET and Relay module screws 4 - M3x8 layer mount screws (Kit) Bottom Level: 5 - M3x5 SKR Mini E3 screws (Reuse Melzi screws) 4 - M2.5x5 Raspberry Pi screws 3 - M4x5 layer mount screws (Reuse from factory PSU) 1 - M4x8 display/layer mount screw All mounts are easily removable as they're separate bodies in the STEP files, so feel free to use different modules if you like. My personal setup is as follows: Relay for SKR/Melzi control Relay for an enclosure heater MOSFET for LED in enclosure MOSFET for ventilation/cooling fan Secondary AC input for heater power Everything else should be self-explanatory. Assemble from rear to front. The rear panel should slide onto the power supply, being careful with the terminals on the AC input - they should be able to slide next to the terminals on the PSU with a little coaxing. Attach the base layer to the PSU and complete all wiring and testing, then repeat for the second layer. Add the display mount at this point too. Once you're happy with everything, the case should slide over everything and a few M3 screws can be used to secure it in place. No supports are required to print, but the case will likely need a brim. Please exercise caution when using the screws that hold the bottom layer to the PSU - they have a maximum depth of 3mm. Make sure your printed part is thick enough or add a washer/spacer to prevent damage to the PSU.
