You can't have too much desiccant and there's space at the rear of the Python AMS enclosure. I already added five front desiccant boxes to the Python AMS enclosure, but I was still seeing humidity readings much higher than with the stock AMS. At first, I attempted a simple remix of another desiccant holder, but as @kahless5876 graciously pointed out, the top and bottom were too thin. I withdrew that model and redesigned the box from scratch in Freecad. The print takes about 81g of PETG and about 3 hours of P1 time. It's straightforward - no supports required, 0.2mm layer height. The cone shaped legs need to be glued to the corners of the base. They provide sufficient room for the PETG tubes, etc. You probably want two of these per enclosure. The box holds about 295g of Dry&Dry.
