🖨️ 3D printing#

🤔 Before Printing 🤔#

We assume you have basic experience with consumer-level 3D printers (BambuLab, Prusa, etc.). This means you know how to properly 3D print STL files with PLA filaments and are familiar with reorienting parts, adding supports, adjusting infill, and modifying print speed to achieve your desired balance of material strength, efficiency, and model detail quality.

  • For more detailed information, you can check out the 3D printing instructions for Lekiwi and SO100 Arm.

  • All the 3D printed parts shown in the demo videos and pictures of XLeRobot were printed with a BambuLab A1 using BambuLab PLA Matte Black.

  • You can also use filaments with better mechanical properties, such as PETG HF, PLA CF, etc., to enhance the arm’s strength.

⏫ Extra Parts for XLeRobot ⏫#

If you already have 2 SO100 Arms and 1 Lekiwi base, you’ll only need 3 additional parts for the XLeRobot hardware version 0.1.0.

(Please also check the Build From Scratch section below, as the parts list differs slightly)

Arm bases#

  • The bases are designed to rotate 15 degrees outward, expanding the workspace area on both sides while enabling smooth collaboration between the two arms.

  • The original forward facing base is also available if you want to keep things simple.

  • The design features a hollow center to save filament. You can insert a used Bambulab filament cardboard spool for added structural support.

Lekiwi base connectors#

  • This component connects the Lekiwi base’s top plate to the IKEA cart bottom. It’s an enhanced version of the Lekiwi base motor mount, redesigned for better stability.

Note

If you’re using a not an authentic IKEA cart, you can adjust the z-axis scale in your slicer software (while maintaining the xy-axis scale) to ensure even pressure distribution between the Lekiwi base and cart wheels.

Thinner Lekiwi base top plate#

  • This is a thinner version of the standard Lekiwi base top plate, used to secure the connectors to the IKEA cart bottom.

  • While the current connection between the Lekiwi base and cart is stable, an upcoming second version will simplify installation on the cart’s metal mesh bottom.
