Modular hygrometer holder, for Ultimate Cereal Filament Drybox

I created this modular holder for GunplaMark's Ultimate Cereal Filament Drybox, because I never liked the hygrometer hanging on top of the filament exit port (unstable angle against gravity). This mod allows to put some accessories in a stable manner inside the drybox, opposite side to the filament exit port. This can be ideal for some people's setups, thus making GunplaMark's system more versatile.

It is made of one base, plus one plug-in of your choice. The base fits where the desiccant basket normally sits.  Currently, there are 5 plug-ins to choose from:

• Square digital humidity sensor adapter.

• Round digital humidity sensor adapter.

• Analog humidity sensor adapter (these can be found cheaply on aliexpress, and require no batteries).

• Label adapter (compatible with GunplaMark's plastic labels).

• Horizontal support to stabiliize the standard GunplaMark's hygrometer holder.

• Added support for analog hygrometer, and other plug-ins.
