Legacy G2 Optimus Prime Cab Extension Upgrade Kit

This upgrade kit requires permanent modification of your Legacy G2 Laser Optimus Prime or Velocitron Scourge, so be warned.

I recommend using Gundam/Hobby nippers to clip the smokestacks off where they connect to the cab. They're made of clear plastic, so be warned, it may be fragile and could bust your figure potentially. I used Sharpie Pro marker to hide where they connected to the cab.

Note: The extended fenders, dually tires, and knee pads are not included, and are from separate upgrade kits.

Setting I used for my profile:

100% infill 

tree supports (slim)

0.20mm layer height

A 3mf file is included with proper settings for ease of printing, I use the Bambu Studios A1.

Use a 1.8mm drill bit on hinge holes for easiest install

Use 1.75mm 3d printer filament to connect hinged parts, twisting the filament as you insert. A toothpick could also work for this.

The parts "Arm Flap 1" and "Arm Flap 2" are mirrored parts, same with the smokestacks. The main arm part "Arm Part x2" does not need to be mirrored.

For the window visor, I used some small dabs of hot glue to hold it onto the windshield, this is still holding well on my figure.

Smokestacks hold onto the arms with 5mm ports, but tend to fall out a little easy, so some superglue is advised to be used in that port.

Spare 5mm tire made in tinkercad included
