Today, we’re using the K8 to print replacement parts and upgrades for itself, specifically a filament guard and a filament holder. [https://www.youtube.com/watch?v=uZvNH5IQbWY](https://www.youtube.com/watch?v=uZvNH5IQbWY) [https://www.youtube.com/watch?v=uZvNH5IQbWY](https://www.youtube.com/watch?v=uZvNH5IQbWY) Watch the video below to follow along: https://www.youtube.com/watch?v=uZvNH5IQbWY Watch Video on YouTube: [https://www.youtube.com/watch?v=uZvNH5IQbWY](https://www.youtube.com/watch?v=uZvNH5IQbWY) ### Step 1: Find the 3D Models - Visit [CNCU.CO.ZA](https://cncu.co.za/PrintUP-3D-Printer/3D%20Parts%20Design/): Navigate to the [3D printer section](https://cncu.co.za/PrintUP-3D-Printer/3D%20Parts%20Design/) on the CNCU website. - Download the [STL Files](https://cncu.co.za/PrintUP-3D-Printer/3D%20Parts%20Design/): Locate the filament guard and holder files. Make sure to download the STL format instead of the object file.

If you’re new to Cura, check out our previous tutorial on setting it up. - Adjust the Model: If the model appears too large for the printer bed: Rotate it flat on the bed. - Snap the model flat using Cura's rotation tool. - If the height exceeds the printer’s maximum capacity (e.g., 80mm), you’ll need to split the model.

Divide it in half (e.g., 52.5mm). Adjust the Z-axis in Cura to achieve this. - Duplicate and Adjust: Create two halves—one for the top, one for the bottom. Rotate and position them appropriately. Alternatively, you can use TinkerCad for precise cutting: - Import the STL file into TinkerCad. - Use transparent shapes to cut the model at your desired height. - Export each half as a separate STL file. ### Step 4: Slice and Print - Import into Cura: Load the halved models. - Add Supports: For overhangs, enable supports: Set support angle to 65°. - Choose “Touching Build Plate” and “Tree” support types. - Set support density to 1% for material efficiency. - Slice the Model: Save the sliced file to a memory stick. ### Step 5: Print the Parts - Transfer the file to your [3D printer](https://buythis.co.za/3d-printers#ai). - Start the print and estimate the time required (e.g., 10–12 hours). - Let the printer run overnight.
