Dry Box Silica Gel Container | Easy printing

This silica gel container is designed to fit neatly into the bottom of the dry box shown in the photos while making efficient use of the available space.

The shape follows the interior of the box, including the central area around the spool holder. The cutouts in the middle also provide convenient finger access, making the container easier to lift out of the dry box when needed.

The container consists of two large mesh panels and separate wall sections that are assembled after printing. This allows all parts to be printed flat, quickly and efficiently. The complete set can fit on a 225 × 225 mm build plate.

The mesh is created directly by the slicer using rectilinear infill with no top or bottom layers, so there is no need to model or print a dense solid surface.

A removable access door allows the silica gel to be refilled without taking the whole container apart. A separate filling funnel is also included to make pouring silica gel into the container easier and cleaner.

Assembly

Before gluing, I recommend first placing all parts together without adhesive to check their orientation.

Apply a small amount of suitable adhesive into the grooves of the bottom panel and insert all wall sections except the removable access door.

Once all walls are correctly positioned, apply adhesive to the corresponding grooves in the top panel and carefully place it onto the assembly.

The wall sections are therefore held between the upper and lower panels, creating a lightweight but rigid container.

The access door should remain removable so the silica gel can be replaced or regenerated when necessary.

The included funnel can be placed into the filling opening to make refilling easier.

Print settings

These are the settings I used successfully.

Bottom panel, top panel and access door:

• Material: PETG

• 20% rectilinear infill

• 6 walls / perimeters

• 0 top layers

• 0 bottom layers

Wall sections:

• Material: PETG

• 20% rectilinear infill

• 3 walls / perimeters

• 0 top layers

• 0 bottom layers

Using 0 top and bottom layers intentionally exposes the rectilinear infill and creates the mesh structure visible in the photos.

The wall parts are numbered to make identification and assembly easier. The required print quantity is included in each filename.

The complete set can be arranged on a single 225 × 225 mm print bed.
