Material 

• black and white filament (PLA, PETG, …)
• USB-C or lighting cable 
• concrete or plaster for base (optional)

Printing 

side panels (white)

Printing the side panels is quite tricky with a FDM printer because of all the wobble. I printed them standing upright, with the long side aligned with the y-axis and I cut the acceleration speeds in half. You will have to enable supports from built plate. Inner supports are not needed, the model contains a few small support beams in the Tesla logo. Those have to be removed after printing as well.

body parts (black) 

These parts are also printed upright. They don't require any supports. Make sure to align the longer side with the moving direction of the print-bed.

base (3D printed or concrete moulded) 

I casted my base in plaster to make the charger heavy at the bottom. This way it won't tip over when handling the cable. It also makes the whole setup more authentic. 3D print the mould in regular PLA and coat the inner surface with oil to ensure that it is detachable. Flexible material like TPU might also be a good option if you plan to reuse the mould.

I've also uploaded a fully 3D-printable version of the base.

Assembly 

1. Put the cable into the channel in the front-center part. It should be about 21cm long as it leaves the inside of the charger. 
2. Press the two center-parts together.
3. Carefully mount the side panels to the center part.
4. Push the charger into it's base and lead out the cable at the back.
