While assembling the printed parts it was necessary to use a 5/16" (8mm) drill bit to clear the holes. Unfortunately this was destructive to some of the openings. This demonstrated two things, the density of the fill was too low, and the hole was printed at the wrong size. As shown earlier with the bearing sockets, printer error needed to be accounted for. In the past, it was usually enough to drill out the holes but a higher infill was used. Since these parts will be subject to high strain they should be printed solidly once the final dimensions are established.
The model was parametric so changing the bolt radius was a simple matter, as it was with the bearing radius. In other CAD programs changing a single dimension could mean a lot more work. Depending on the versatility and friendliness of the program it could mean moving every part one at a time. Since changes were being made, the length of the bolt holes were also increased.
