This is a simple drybox that i made. All you need extra is an 12mm rod to put the filament onto. For mounting the side pieces you need m4 nuts and m4x16 bolts. For mounting the hygrometer you need m5 nuts and m5x16 bolts. The passthrough in the pictures is a pneumatic one for a fi4 tube. In the future i will make a 3d printed one.
