It appears that you have provided a detailed guide on various modifications to improve the performance of a 3D printer, specifically for the Creality Ender 3. Here's a summary of the modifications and their costs: 1. Hotbed insulation modification: * Cost: 2/5 * Difficulty: 4/5 * Goal: Improve thermal insulation under the hotbed * Mean: Add a thermal isolation material under the hotbed 2. Glass cover and heater PCB improvement: * Cost: 1/5 * Difficulty: 1/5 * Goal: Improve close contact between the top cover glass and the heater PCB * Mean: Use simple paperclips to achieve better contact 3. Extrusion precision improvement: * Cost: 1/5 * Difficulty: 1/5 * Goal: Improve extrusion precision * Mean: Add simple springs tensioner on the belt 4. Motor noise reduction: * Cost: 4/5 * Difficulty: 3/5 * Goal: Minimize sound generated by the running printer * Mean: Replace original motor stepper drivers with TMC 2208 Drivers 5. Hotbed leveling improvement: * Cost: 1/5 * Difficulty: 1/5 * Goal: Catch the hotbed when it's hot without using adjustement screw * Mean: Add a simple printed part to handle the hotbed 6. Axis guide lubrication: * Cost: 1/5 * Difficulty: 1/5 * Goal: Reduce noise and improve axis guide performance * Mean: Use refining base oil with lithium soap thickening, antioxidant, and anti-rust additives Overall, these modifications aim to improve the thermal insulation, extrusion precision, motor noise reduction, hotbed leveling, and axis guide lubrication of the 3D printer. The costs are relatively low, ranging from 1/5 to 4/5, and the difficulties vary from 1/5 to 4/5. It's worth noting that some of these modifications may require technical expertise and specialized tools, such as a multimeter and leatherman tool. Additionally, the cost estimates may not include the cost of shipping or any additional components required for the modifications. If you're interested in trying out these modifications, I recommend carefully reading through each step and watching the provided videos to ensure that you understand the process before starting.
