**Frame built**

==== Lower Frame ====

   - - We tap holes with the taps into alu-extrusions to merge it with 3d printed mcs I-connertors (60x60) and endkappe".
  -  - We connect two horizontal extrusions with other two and screw mcs winkel-stabil (40x20) together.
  -  - We add angle connectors (mcs_winkel_stabil_40x20) to support the new struts
  -  - We connect third horizontal bar to the just build rectangle 120mm from the rear horizontal extrusion using angle connectors (mcs_winkel_stabil_40x20)
  -  - We add end covers (mcs_endkappe_40x20) to the sides of the foremost and hindmost extrusions
  - 
==== Vertical Frame ====

  - combine 3 extrusion (300mm) to form a "U"-Form using angle connectors (mcs_winkel_stabil_40x20)
  - reinforce using corner connectors (mcs_l-verbinder_stabil_60x60)
  - add end covers (mcs_endkappe_60x20) to the "bottom" of the "U"

==== Connect everything ====

  - connect the vertical frame (invert the "U") with the lower frame using cube connectors (mcs_wuerfelverbinder_20x20)
  - add angle connectors (mcs_winkel_stabil_40x20) to strengthen the connection between the long struts (400mm) and the vertical frames "legs"
  - add corner connectors (mcs_l-verbinder_stabil_60x60) to finalize
