Simple printer-friendly chess set

This is a set of simplified chess pieces I made because my flight was going the next day and I wanted a travel chess set, then made minor improvements after I returned home.
Any criticism is welcome and appreciated.

It is simplified, not minimalist, because the pieces are supposed to be easily distinguishable. Further, the pieces are designed to be easy to print, without supports, at high speeds, with low resolution, low infill and at small scales.

The sets in the pictures are printed with 0.2mm resolution and 20% infill, but that really shouldn't matter.

The default size is already rather small with heights from 22mm to 36mm, but you should be able to scale them as you wish without any issues.
