Lock-in-place in-spool desiccant (silica) container with pillars

This model is the exact same as @PhilipSorensen's v2 remix for small silica gel containers, but I've added additional pillars to help prevent layer separation of the basket weave.

PsychProd was the original designer and PhilipSorensen remixed the design that I modified. This modification adds additional support pillars.
