Major improvements:

• Reinforced Front and Rear Chassis as it broke several times in the very same spot. (for those interested: I just added a pair of 0.4mm slots to the model so the slicer generates perimeters around them ;-) )
  PETG does not work well, I highly recommend using PCTG which has much better impact strength.
   
• Remove friction from shock cutout lower arms,  shocks can extend fully now. This should be replaced in the original design as it is a design flaw.
  Pro-Tip: use Hard TPU for lower arm and PCTG for upper arm (or vice versa). This combo survived some nasty crashes even a store-bought car would not have survived.
  
• Gear Box! Addon fits original design. Not 100% happy with durability, but it surely works.
  
• Towers with extensions for off-the-shelf body (Provided by @Machhin)
  Print towers with HARD TPU (Extrudr for example). Basically unbreakable)

Minor upgrades / tweaks

• Topdeck.Body2: Added hole for RC antenna
• Chassis.Body1&Body2 Batterymount.Body1&Body3: Added hole for battery mount reinforcement (backward compatible)
• Motorplate.Body1: Decrease hole for big bearing to 10.1mm (fits 5*10*4 bearings)
• Motorplate.Body1: Decrease hole to 3.4 (Clearance Hole Size Medium Fit as per https://engineersbible.com/clearance-hole-metric/)
• Towers: Remove friction from shock tower standoff (INJORA 100mm shocks affected, maybe others too?!)
• Diffgears screw-direction swap and labels Front RL and Rear RL (as we built 4 out of 4 the "wrong" way around / CW direction)
• Re-located square nuts on servo mount to the inside for easier assembly
• Added cut-out for 3010 motor cooling fan (I prefer a different fan though, easier to mount, cheaper, works for most 3650/60 motors but not Rocket V2) 

Modpack with improvements and addons for Robak V2.1.
I don't know if compatible with releases later than V2.1
