Kossel Delta Printer Enclosure

thingiverse

This enclosure builds upon an existing frame, ensuring full access to the print from any angle. To accommodate different configurations and sizes, some modifications may be necessary. Step files are provided for altering the CAD as needed. I used clear polycarbonate sheet, specifically 1/4" thick material, for the doors and vertical edges. The sheets were cut using a jigsaw and then smoothed with a belt sander. However, working with a jigsaw proved to be frustrating due to its tendency to wander, and I found it challenging to achieve smooth cuts. To secure the center seams, I implemented a 15° miter joint. Although this added some complexity, it ensured a sturdy connection. Polycarbonate is an excellent choice for this project, as it resists cracking better than acrylic. To keep the doors shut, I employed springs, but alternative options like magnets or latches could also be used. Once constructed, this enclosure will expose any misalignment in your towers, making auto-calibration highly recommended. One beneficial side effect of stiffening the structure is a significant reduction in ghosting. Considering installing torsional tie rods to the top half may further enhance the enclosure's performance. To monitor temperature within the chamber, I set the firmware to recognize an additional hotend and connected a thermister to the motherboard pins. This allows for real-time temperature display on the screen. Since I primarily print with ABS, I opted for EEB settings instead of RAMP_1.4_EFB. Additionally, I removed the part cooling fan from the hot end to minimize mass movement. With the bed set at 95°C, the chamber stabilizes at around 45-50°C. For assembly, you may find the following components useful: * Hinges: McMaster-Carr #18455A71 * M4 fasteners with T nuts: Amazon (search for "M4 fasteners with T nuts") * Door sealing foam: Amazon (search for "door sealing foam") If your printer is not large enough to handle the entire top panel, you can chop it into three separate pieces. The vertical members, including doors and edges, measure 24" in height, while the doors are 6" wide and the edges are approximately 1.5". To accommodate these dimensions, a 24" x 48" panel or sheet should suffice.
