How to Print & Assemble The OLIT-S1

If you want to save this How-To instruction as a pdf file (and print it out later if needed), simply copy the URL of this page and paste it to https://www.printfriendly.com/ . Printfriendly will generate a printer-friendly pdf of the page with all the texts and images for you.

All of the STL files are really straight forward to print. All you need to do is load them into your slicer software (I use Cura), select your desirable settings (e.g. layer height, infill percentage, etc.) and slice the parts. I used 0.4mm nozzle 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:

• 10mm dia x 2mm thick N42 Neodymium magnets (LINK) | Qty: 58-off
• 5mm dia x 3mm thick N42 Neodymium magnets (LINK) | Qty: 62-off
• 3mm dia x 2mm thick N42 Neodymium (LINK) | Qty: 26-off
• 5mm dia x 20mm L Dowel Pin (LINK) | Qty: 14-off
• 5mm dia x 28mm L Dowel Pin (LINK) | Qty: 12-off
• 10mm dia x 330mm L Steel Rod (LINK) | Qty: 4-off
• 10mm dia x 1500mm L Steel Rod (LINK) | Qty: 4-off
• Ball Bearing 35mm O.D x 17mm I.D x 10mm Race Width (LINK) | Qty: 2-off
• 5mm dia Steel Bearing Ball (LINK) | Qty: 36-off
• Polyester Cord String 1mm dia (LINK) | Qty: 20 meters
• M3 x 10mm Hex Socket Cap Screw (LINK) | Qty: 4-off
• M3 Hex Nut (LINK) | Qty: 4-off
• Super glue (LINK) | Qty: 1 bottle

At this step, all I want you to do is view the fully completed OLIT model as well the main sub-assemblies to get a good understanding of each section of the model and where all the parts 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 load the STL files in “STEP_00” folder using your CAD software or Slicer.

In order to build each section of the OLIT precisely, you’ll need to use a combination of assembly fixtures. These fixtures can be found in folder “STEP_01” (refer to the photos below):

• 1x Assembly Fixture_1
• 1x Assembly Fixture_2
• 1x Assembly Fixture_3
• 1x Assembly Fixture_4

Parts required (refer to the photos below):

• 1x Base (a)
• 1x Base Lid (b)
• 2x Pulley_01 (c)
• 1x Base Control Station Roof (d)
• 1x Base Control Station (e)
• 1x Base Control Station Support Beam (f)
• 2x Dowel Pins (5mm dia x 20mm L) (g)
• 20x Magnets (3mm dia x 2mm thick) (highlighted in RED)
• 8x Magnets (5mm dia x 3mm thick) (highlighted in RED)
• 20x Magnets (10mm dia x 2mm thick) (highlighted in RED)

Assembly process:

1. STEP 2a: Glue 4x magnets (5mm dia x 3mm thick) into their pockets on the Base
2. STEP 2b: Glue 4x magnets (5mm dia x 3mm thick) into their pockets on the bottom of the Base Lid. Insert 2x Pulley_01 to the Base Lid and secure them with the Dowel Pins
3. STEP 2c: Glue 10x magnets (3mm dia x 2mm thick) into their pockets on the bottom of the Base Control Station Roof
4. STEP 2d: Glue 10x magnets (3mm dia x 2mm thick) into their pockets on the top of the Base Control Station. Glue 20x magnets (10mm dia x 2mm thick) into their pockets on the bottom and side of the Base Control Station
5. STEP 2e: 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
6. STEP 2f: Glue the Base Control Station and Base Control Station Support Beam to the Base (note that the text on the Base must be visible as shown in the Front View pic below). DO NOT glue the Base Control Station Roof to anything!!!
7. Finally, place the Base Control Station Roof onto the Base Control Station (the magnets should keep them together)

* Please note: If you are planning to update your OLIT-S1 to the S2 version, please use the new version of the “QD Claw_Upper Arm_RH” and “QD Claw_Upper Arm_LH” from the OLIT-S2 files. Do NOT use this file from the OLIT-S1.

Also, the “QD Claw_Lower Arm_RH“, “QD Claw_Lower Arm_LH“, “QD Claw_Upper Arm_Pad_RH“, and “QD Claw_Upper Arm_Pad_LH” are no longer required for the OLIT-S2

Parts required (refer to the photos below):

• 1x ALL sub-assemblies from previous STEP’s
• 4x Steel Rods (10mm Dia x 1500mm L)

Assembly process:

1. STEP 15a: Stack Launch Tower_Section 1 onto Base. Ensure the orientation is correct – see picture below. Tips: 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 15b: Install 4x Steel Rods (10mm Dia x 1500mm L). If you don’t have these Steel Rods, you’ll need to print a number of Alignment Pins (10mm Dia x 50 mm L) from “STEP_15” folder and use them to align/glue the Launch Tower sections together as you stack them
3. STEP 15c & STEP 15d: Keep stacking until Section 7
4. STEP 15e: Slide the Chopsticks & Carriage Assembly over the top and slide it down carefully until it touches the “Stop” in Section 1. Alternatively, you can just insert something long through the Tower to 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 15f: Continue stacking with Section 8, 9a & 9b. Your OLIT is now fully stacked!
6. STEP 15g: Install the QD Claw to the QD Arm – the magnets should keep them together. You can also glue them together if you prefer.
7. STEP 15h: Slide the QD Arm Carriage over the rear Column of Section 4 & 5 (see pictures below). Use the 2x QD Arm Carriage Brackets to hold this part firmly in position.

Parts required (refer to the photos below):

• 1x Fully stacked OLIT from STEP 15
• 1x Cable (about 15 – 20 meters long)

Assembly process:

1. Run cable through the pulley systems of the OLIT. If needed, use “10_Pulley Cable.stl” in folder “STEP_00” for guidance

Parts required (refer to the photos below):

• 1x OLIT
• 1x Starship-S1 (this is a standalone model and you’ll need to purchase separately)
• 1x Booster-S1 (this is a standalone model and you’ll need to purchase separately)

Assembly process:

1. Place the Starship-S1 and Booster-S1 (with Orbital Launch Pad) next to the OLIT
