Air propelled Car with tapered axels

thingiverse

To avoid the issue of 5mm diameter axels not fitting into the 4.7mm diameter holes (printed), I crafted tapered axels that snugly fit in the holes. The body was printed at 15% infill and 0.27mm layer height, with exterior support. Other parts were printed at 50% infill; only the axels required exterior support. As a reference, original components are provided.
