Mammut - Giant printer.

cults3d

It appears you've provided a detailed list of components and materials needed for a 3D printer build. I'll break down the list into categories: ### Frame Components - **Frame Material**: Plastic gussets, 40x40x2 mm square tubing. - **Tubing Lengths**: - 2 pieces @ 1300mm (lengthwise). - 3 pieces @ 620mm (ends and top). Note: Aluminum might not be the best choice for these; steel would be more durable. - 2 pieces @ 500mm (Z-axis), placed 390mm from the front end gusset. ### Lead Screws - **Lead Screw Specification**: 8x8 mm, 500 mm long. Includes nuts and can fit into Z shaft adapters. You can find suitable lead screws with copper nuts [here](https://www.banggood.com/500mm-Lead-Screw-8mm-Thread-2mm-Pitch-Lead-Screw-with-Copper-Nut-p-982941.html?p=HD240528697332015103). ### Hot End Cooling - **Hot End Fans**: 40x40 mm for cold end cooling. - **PLA Cooling Fans**: Two 35x10mm blower fans. You can find similar blower fans [here](https://www.banggood.com/Volcano-Hot-End-Eruption-Heater-Block-Heating-Block-For-3D-Printer-Accessories-p-1014475.html?p=HD240528697332015103) and [here](https://www.banggood.com/Heatsink-12V-0_1A-2-Pins-CPU-Cooling-Fan-PC-Computer-40x40x10mm-p-920618.html?p=HD240528697332015103&cur_warehouse=CN). ### Z Axis Fan - **Z-Axis Blower Fan**: A 35x35x10 mm fan can be used with some modification. You can find a compatible heatsink [here](https://www.banggood.com/Aluminum-Heatsink-Cooling-Fan-For-LattePanda-Matching-Acrylic-Case-p-1092769.html?p=HD240528697332015103&cur_warehouse=CN). ### Motor and Stepper Specifications - **Steppers**: 92 oz in/65 Ncm for X, Y, and extrusion. - **Motor Note**: The 30 tooth pulleys on the X- and Y axes require strong motors to achieve high travel speeds of up to 300 mm/s. ### Extruder Gear - **Extruder Gear**: A ~11 mm gear is needed. You can find a compatible MK7 or MK8 extruder driver feeder gear [here](https://www.banggood.com/2Pcs-MK7-MK8-Extruder-Driver-Feeder-Gear-Wheel-40Teeth-11mm-Bore-5mm-For-3D-Printer-p-1036149.html?p=HD240528697332015103&cur_warehouse=CN). ### End Stops - **Homings**: - **Microswitch for X**: Uses a microswitch for homing. - **PiBot Optical End Stops for Y and Z**: Includes parts for installing all switches. The X- and Z-switch brackets are attached to the frame with high strength double-sided tape, providing a secure attachment. To summarize: - You need various components for building your 3D printer, including the frame, lead screws, cooling fans, extruder gear, motors, and end stops. - Some components require modification or replacement to ensure compatibility or optimal performance.
