Procedure

1. Gather the two Bottom Bases and the Bottom Mid-Cross and assemble them using four M3-0.5x5 screws and two M5-0.8x10 screws with two M5 locknuts. Note the M5 screws and locknuts are installed in two center holes and are used to prevent the inner-basket panels (the ones with tabs and matching slots) to flex slide out of the slots during assembly.

   
2. Now take the two Panel Basket Mid Crosses and install them in the Bottom Mid-Cross using eight M3-0.5x5 screws.

   
3. Get the Panel Inner Baskets (110-016) and insert their tabs in the slots at the bottom plate.

4. Screw them in from the inner faces of the Middle Crosses.

   
5. Next take the Top Mid-Cross and fix it in place using eight M3-0.5x5 screws.

   

   Make sure to leave the two mounting holes in the middle free.
6. Now take the two front/rear U-Frames and put them in place using eight M3-0.5x5 screws per frame.

   Front three screws

Assembly notes

Don't forget on adding the two M5-0.8x10 button head cap screws and the M5 locknuts at the bottom plate to ensure the tabs in the middle cross braces don't pop out of place.
