Hello! This modular enclosure is geared towards use with a BTT SKR 3 EZ, RaspberryPi 4 and Klipper. Hopefully with my release, someone else will enjoy the design and get some use out of it as well!
I wanted a console for outside the main printer enclosure. This allows the printer enclosure to achieve higher temps without as much worry. Another great advantage is any adjustment made at the printer during a print can be done so without having to open the printer enclosure, reducing the risk of warping due to drafts. Another additional feature is, most of what the SKR3 has to offer has been routed to the back of the enclosure for easy plug and play, without having to open the enclosure. Easy side panel access to the power switch, micro USB, and the Raspberry Pi's USB and Ethernet port for added convenience.
Has TONS of cooling! For some, all the fans may not have to be used. For myself and my warmer environment, I needed the extra cooling. The way I have it set up, the fan holes are sealed with a single layer to be cut out as needed. This also helped with curling during the print. I used PETG for everything. The enclosure is split into two pieces to fit within my printer's constraints while printing. The printer I used was the Ender 3 V2. More photos coming soon to show wire routing and the completed console. Currently, the status of my build is the painting and sanding phase.
I ended up not using the JST 2.54mm connectors soldered to the PCB on the back of the console. Instead, I just ran cables through the holes for ease and convenience. I also recommend for the fans to hook them all up to a buck converter to turn the speeds down if needed.
The enclosure houses the main Power supply (Mean well LRS-350-24) as well as a NOYITO AC120v to 5v 3amp DC PS for the Pi, BTT Relay v1.2 for automatic shutdown and a Mosfet Bed Power Module rated at 25 amps.
Fabrication tips I recommend:
- When assembling the two halves together before using CA glue, Epoxy etc. Put the 5015 fan grills on, use masking tape to help with alignment if needed and then screw the top cover on for best alignment, then glue by letting the adhesive flow into the seam being careful not to permanently glue the top or the fan covers on by accident. Once tacked into place, the top cover and fan grills can be removed for the final gluing. Depending on variables, some sanding and adjustment may be necessary for the best fit before joining the halves together. The model was made to have gaps filled, outside sanded and painted. The front half of the console uses a single layer for extra support that needs to be cut away before assembly. When printing the front of the console, the front should face upwards on the build plate.
