The first print that I did consisted of the dashboard and differential components. I’m using hatchbox PLA (1.75 mm) for the dashboard and Hatchbox ABS (1.75 mm) for the differential, silver and black respectively.  I decided to go with ABS plastic for the differential due to the increased rigidity it has over PLA and PETG, able to take more strain and stress. I also printed the differential covers in ABS plastic for increased rigidity.  Infill for both was 25 percent, as well as a 0.15 mm layer height. 

The next print that I did was the mid section for the body of the vehicle. For this I decided to go with white ABS plastic (1.75 mm) for increased structural rigidity.  30 percent infill for the print, 0.15 mm layer height.  For a first time print in an open air non controlled environment I was surprised it did not warp when printing.  Total print time for this component was 13 hrs and 44 minutes.

While I was waiting on prints to finish for the rest of the body I began to assemble differential.  I used 10x15x4 mm Stainless Steel Ultra Seal bearings for the inside of the differential.  They can be found here: https://www.bocabearings.com/products/smr6700-uu-7-ps2-2748
