Where are the 3 rectangular base connector parts for the IKEA cart base in XLeRobot 0.4.0?

Hi, I’m trying to build the XLeRobot 0.4.0 IKEA cart base.

In the hardware README, the image under “No need to adjust the base connector this time, just print the washers...” shows 3 rectangular base connector parts and 4 C-shaped washers.

I found the C-shaped washers in XLeRobot_0_4_0_extra.stl, but I cannot find the 3 rectangular base connector parts.

I checked:

• hardware/XLeRobot_0_4_0_extra.stl
• hardware/XLeRobot 0-3-0 new wheel connector.stl
• hardware/XLeRobot_0_3_0.3mf
• hardware/step/XLeRobot_040/XLeRobot040_dualwheelbase.step

Could you let me know which file contains the 3 rectangular base connectors, or whether they are no longer needed for the 0.4.0 IKEA cart setup?

0.4.0 is adapting a dual-wheel setup other than omni wheels for faster speed, better passability and more stable control. So there's no rectangular connectors. Please refer to https://xlerobot.readthedocs.io/en/latest/hardware/getting_started/assemble_2wheel.html
