The STL package of this model includes an “All-In-One” Print Profile created for Bambu Lab H2 Series 3D printers. If you don’t have a H2 Series but any other printers from Bambu Lab, simply load the profile in Bambu Studio and change the printer setting to your printer. If you are new to 3D printing and never use a “All-In-One” Print Profile before, follow this instruction: How to use Bambu Studio’s All-In-One Print Profile

If you don’t have access to any Bambu Lab 3D printers. We recommend you to download Bambu Studio and load our Profile up so you can replicate the print settings that we use for each part of the model in your own slicer. Most parts of the model can be printed with a standard 0.4mm Nozzle. However, to achieve the optimum result for parts with small details, we strongly recommend using a 0.2mm Nozzle

So now you’ve got all your parts printed? Great! Let’s assemble the model!

I’ll take you through the assembly process step by step but before that, you need to purchase some items:

• 3mm dia x 2mm thick N42 Neodymium (LINK) | Qty: 100-off
• 5mm dia x 3mm thick N42 Neodymium magnets (LINK) | Qty: 138-off
• M3 x 10mm Hex Socket Cap Screw (LINK) | Qty: 12-off
• Rubber Band (LINK) | Qty: 1-off
• Super glue (LINK) | Qty: 1 bottle

At this step, all I want you to do is try to stack all the parts together to get a good understanding of where they are located. Because there are a lot of magnets you need to fit during the assembly process, doing this first step will give you an idea of how to fit the magnets in each part correctly. Please use the files in STEP 01 folder, and the photos below if required.
