This is a 3D printing project instructions for building a dual hotend mount, specifically the "i3 Magnetic Dual Hotend Mount" by Karl Zhao. The project uses the Twin Extruder design by Tim Edwards and requires some modifications to be made after printing. Here's a breakdown of the instructions: **Printing** * Print all parts without supports. * Use ABS or another temperature-resistant plastic for the hotend mount. * Use PLA for the rest of the parts. * Recommended infill: 20-30%. **Assembly** 1. Drill 15mm holes for LM8UU bearings in the carrier and hotends. 2. Drill 5.5mm centering holes in the left and right extruder mounts. 3. Drill 5.5mm opposing hole in the carrier. 4. Drill 5mm hole for centering rod in the carrier. 5. Drill 5mm hole in the left and right hotend mounts for oppositing rods. 6. Drill/fine 6mm holes for magnets, making sure not to drill on the bottom of the hole. **Software** * Use Slic3r 1.3.0 dev or later, as it includes experimental IF functions. * The project includes a startup script and tool change script that need to be modified for dual extruder selection. **Startup Script** The startup script is designed to: 1. Raise the Z-axis to 10mm. 2. Home the X and Y axes. 3. Home the Z axis. 4. Move the right hotend to position X161. 5. Park the right hotend at X171. 6. Level the bed using G32. **Tool Change Script** The tool change script is designed to: 1. Switch between the two extruders using T0 and T1 commands. 2. Move the hotends to their respective positions (left or right). 3. Park the opposing hotend at its designated position. 4. Fine-tune the height of the second extruder. **Tips** * Make sure to drill all holes carefully, as the LM8UU bearings need to fit perfectly into their respective holes. * Use magnets that touch each other for good hold power. * Install magnets last, after drilling/fine-tuning all holes. Overall, this project requires some attention to detail and careful assembly. However, with the provided instructions and scripts, it should be possible to build a functional dual hotend mount.
