The STL package of this model includes an “All-In-One” Print Profile created for Bambu Lab X1 and P1 Series 3D printers. If you intend to use any of those printers to print the model, follow this instruction to print all parts: How to use Bambu Studio’s All-In-One Print Profile

If you don’t have access to any Bambu Lab X1 and P1 Series 3D printers. All of the STL files are really straight forward to print. All you need to do is load them into your slicer software (e.g. Cura), select your desirable settings (e.g. layer height, infill percentage, etc.) and slice the parts. I used 0.4mm nozzle and 0.2mm layer height to print all parts of this model

Please note: I already saved the STL for each part in the orientation I printed them on my FDM printer. 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: 3-off
• 3mm dia x 2mm thick N42 Neodymium (LINK) | Qty: 16-off
• 3mm dia x 20mm L Dowel Pin (LINK) | Qty: 41-off
• 3mm dia x 10mm L Dowel Pin (LINK) | Qty: 18-off
• Ball Bearing 19mm O.D x 10mm I.D x 5mm Race Width (LINK) | Qty: 2-off
• Polyester Cord String 1mm dia (LINK) | Qty: 20 meters
• Super glue (LINK) | Qty: 1 bottle

At this step, all I want you to do is carefully review the 3D model of each sub-assembly, as well as the fully assemble OLIT-XS3. As this is a fairly complex model to assemble, doing this first step will give you a good understanding of where all individual parts are located.

Please load the STL files in STEP 01 folder in your slicer or CAD software, and the photos below if required.

Please DO NOT print any STL files in STEP 01 folder – they are for assembly guidance purpose only!

Parts required (refer to the photos below):

• 1x Base (a)
• 1x Base Lid (b)
• 2x Pulley 1 (c)
• 1x Base Control Station Roof (d)
• 1x Base Control Station (e)
• 1x Base Control Station Support Beam (f)
• 1x Base Shield_01 (g)
• 1x Base Shield_02 (h)

• 2x Base Pipe Cover (j)
• 2x Dowel Pins (3mm dia x 20mm L) (k)
• 16x Magnets (3mm dia x 2mm thick) (highlighted in RED)

Assembly process:

1. STEP 2a: Glue 8x magnets (3mm dia x 2mm thick) into their pockets on the Base
2. STEP 2b: Glue 4x magnets (3mm dia x 2mm thick) into their pockets on the bottom of the Base Lid. Insert 2x Pulley 1 to the Base Lid and secure them with the Dowel Pins (3mm dia x 20mm L)
3. STEP 2c: Glue 4x magnets (3mm dia x 2mm thick) into their pockets on the Base Control Station Roof
4. STEP 2d: Fit the Base Lid to the Base (the magnets should keep them together). At this STEP, I highly recommend you to fill the cavity in the Base with something heavy (e.g. sand, steel bars, etc.) to make the Base as heavy as possible. This will help increase the stability of the OLIT once you’ve completed the model
5. STEP 2e/f: Glue the Base Control Station and Base Control Station Support Beam to the Base. DO NOT glue the Base Control Station Roof!!!
6. STEP 2g: Place the Base Control Station Roof onto the Base Control Station (the magnets should keep them together)
7. STEP 2h: Glue the Base Shields, and Base Pipe Covers to the front of the Base (see pic below)

Assembly process:

1. STEP 5a: Carefully place the Launch Tower_Section 1_Column on a flat surface
   

   Please ensure that the sacrificial base is intact throughout STEP 5 assembly process. DO NOT remove the sacrificial base until the final STEP 5e

2. STEP 5b: Slide the Assembly Tool into the Launch Tower_Section 1_Column
3. STEP 5c: Slide 4x Launch Tower_Section 1_Vertical Support Frame in between the 4x individual columns. Ensure that the bottom faces of each Vertical Support Frame touches the top face of the Assembly Tool
   

   You can put some elastic bands over the columns to keep them upright, this also helps secure the Vertical Support Frames in place.

4. STEP 5d: Glue 2x Horizontal Support Frames to the Vertical Support Frames, then glue all 4x Vertical Support Frames to the 4x Columns
5. STEP 5e: Once the glue is cured, remove all the sacrificial base, then the Assembly Tool. The Assembly Tool can be reused to build the next Launch Tower Section

Parts required (refer to the photos below):

• 1x ALL sub-assemblies from previous STEP’s
• 36x Dowel Pin (3mm Dia x 20mm L)

Assembly process:

1. STEP 14a: Stack Launch Tower_Section 1 onto Base. Use 4x Dowel Pins (3mm Dia x 20mm L) for alignment. Ensure the orientation is correct – see picture below.
   

   Before stacking, to make the OLIT more sturdy & stable, you can make the Base as heavy as possible by opening the Base Lid and fill the entire Base’s cavity with something heavy (e.g. sand, metal bars, concrete, etc.) and refit the Base Lid.

2. STEP 14b: Stack Launch Tower_Section 2 onto Launch Tower_Section 1. Use 4x Dowel Pins (3mm Dia x 20mm L) for alignment. Ensure the orientation is correct. Continue stacking until Launch Tower_Section 7
3. STEP 14c: Slide the QD Arm Carriage over the rear Column of Section 4 & 5 (see pictures below) until it hits the “Stop” in Section 4
4. STEP 14d: Slide the Chopsticks & Carriage Assembly over the top of Section 7 and slide it down carefully until it hits the “Stop” in Section 1. Alternatively, you can just insert something long through the Tower to temporarily hold the Chopsticks & Carriage Assembly there near the top (which is probably better because you want to keep it closer to the top of the OLIT to run the cable in the next STEP)
5. STEP 14e: Finish stacking with Section 8, 9a & 9b. Your OLIT is now fully stacked!

Parts required (refer to the photos below):

• 1x Fully stacked OLIT from STEP 15
• 1x Cable (about 3 – 4 meters long)

• 2x Vertical Outer Shield_Bottom (b)
• 6x Vertical Outer Shield (c)
