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. We strongly recommend using a 0.2mm (or 0.25mm) Nozzle to print this model!

Please note: The STL for each part was saved in the recommended orientation to print on FDM printers. Hence, when you load the STL in your slicer software, you don’t need to orientate them again, unless you want to try to print them in a different orientation.

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:

• 5mm dia x 3mm thick N42 Neodymium magnets (LINK) | Qty: 44-off
• 3mm dia x 2mm thick N42 Neodymium magnets (LINK) | Qty: 8-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 ‘BOOSTER-XS4 Assembly.stl’ and the photos below if required.

Assembly process

1. STEP 4: Glue 6x (5mm dia x 3mm thick) magnets into their locations on the top face (3x) and bottom face (3x) of the Booster Common Dome Section

Parts required (refer to the photos below)

• 1x Booster CH4 Tank Section (a)
• 6x Magnets (5mm dia x 3mm thick) (highlighted in RED)

Assembly process

1. STEP 5: Glue 6x (5mm dia x 3mm thick) magnets into their locations on the top face (3x) and bottom face (3x) of the Booster CH4 Tank Section

   Please note: The 3x magnets on the top of the Booster Common Dome Section slightly protrude out of their pockets (approx. 1mm)

2. STEP 6b: Glue 4x (3mm dia x 2mm thick) magnets into their locations on the side of the Booster Common Dome Section

Parts required (refer to the photos below)

• 1x Hotstaging Ring (a)
• 6x Magnets (5mm dia x 3mm thick) (highlighted in RED)

Assembly process

1. STEP 7: Glue 6x (5mm dia x 3mm thick) magnets into their locations on the top face (3x) and bottom face (3x) of the Hotstaging Ring.
   

   Please note: The 3x magnets on the top of the Hotstaging Ring slightly protrude out of their pockets (approx. 1mm), whilst the 3x magnets at the bottom should be pushed all the way into their magnet holes (they should sit approx. 1mm below the surface of the holes)

Parts required (refer to the photos below)

• 4x Grid Fins (a)
• 1x Interstage Section from STEP 6 (b)
• 4x Magnets (3mm dia x 2mm thick) (highlighted in RED)

Assembly process

1. STEP 8a: Glue 1x (5mm dia x 3mm thick) magnet into the magnet hole at the end of each Grid Fin
2. STEP 8b: Insert all 4x Grid Fins into the Interstage Section

Parts required (refer to the photos below)

• 1x Booster Aft Section from STEP 2 (a)
• 1x Booster LOX Tank Section from STEP 3 (b)
• 1x Booster Common Dome Section from STEP 4 (c)
• 1x Booster CH4 Tank Section from STEP 5 (d)

Assembly process

1. STEP 9a: Glue 1x (5mm dia x 3mm thick) magnet into the centered hole at the bottom face of the Booster Inner Compartment (Top), and Booster Inner Compartment (Bottom). Then assemble both parts together
2. STEP 9b: Stack all the sections together

Parts required (refer to the photos below)

• 1x Booster Basic Stand
• 3x Magnets (5mm dia x 3mm thick) (highlighted in RED)

Assembly process

1. STEP 11a: Glue 3x (5mm dia x 3mm thick) magnets into their locations on the top face of the Basic Stand
   

   Please note: These magnets on the Basic Stand should attract the ones on the Thrust Puck

2. STEP 11b: Place the BOOSTER-XS4 on the Basic Stand.
   

   Please note: There are 2 options to place the Booster on the Basic Stand. Option 1 is simple and straight forward but less secured. Option 2 is more secured but you’ll need to remove the Booster Thrust Puck (you can use a pen and push it out via the hole at the bottom of the Booster Aft Section) and rotate it 180 degree

And that’s it! Congratulations, you have completed your 1:200 BOOSTER-XS4 model!
