The silica gel box is made to hold loose silica gel (desiccant) granules and to be fixed in a filament box. When planning the installation and during operation, it is important to ensure that the silica gel box does not prevent or even block the rotation of the filament spools and the smooth unwinding of the filament.

Safety Guidelines

Safety first! Read and follow the assembly instructions and the operating manual!

Read the entire assembly instructions and operating manual carefully and adhere to the instructions and safety guidelines. If anything is unclear, simply contact support (support@3d-druck-vorlagen.de). In the 3D print files for this project, the instructions and operation manual are also attached as PDF, keep it because you may need it later. A one-page quick guide is also included in the files with a link to this page – you will always find the latest version of the instructions and the operating manual here. If you are giving the project to someone else, then print out the instructions, operation manual and, above all, the safety instructions and pass them on with the project.

Before you start the project, also check whether the project meets the safety regulations of your respective country.

Legend: Warnings and Symbols

Safety instructions for this 3D printing project

Never eat silica gel granules / desiccant – toxic!

Never leave the filled silica gel box open and keep it out of the reach of children and animals!

Do not leave the 3D printer unattended while printing! If the printing is interrupted or the 3D printer makes unusual noises, switch off the 3D printer immediately, check the filament box and the filament feed!

Also read through, follow, and keep the operation manuals and safety instructions for the purchased parts!

Attention for all purchased parts: Before assembling, check whether they meet the safety regulations in your country and whether the dimensions, function and stability are fine. Repeat this safety check at regular intervals and before using the project. If a part is damaged or unsuitable, do not continue to use the project until the affected part has been replaced.

Attention for all self-printed parts: Due to incorrectly set printing parameters, poor material, incorrect material selection, poor layer adhesion and other reasons, these can sometimes not meet the requirements needed on them and thus break, fail or their functionality cannot be guaranteed. In the event of a break, the parts can splinter and the fracture surface leave sharp edges. Take particular care when replacing these parts, there is a risk of cuts! Check 3D printed parts for cracks, stability and functionality at regular intervals and before using the project. If a part is damaged or unsuitable, do not continue to use the project until the broken part has been replaced with a new, improved part.

Do not put the 3D printed silica gel box in the oven to dry the silica gel, the components can warp and become unusable.

Always do the safety check before 3D printing

Before printing, check if the silica gel box is well closed and that it sits securely in the clip!

Before printing, check whether the silica gel box or the clip are touching or blocking one of the filament spools!

Check the locking mechanism when changing the silica gel granules

When changing the granules, check whether the locking mechanisms of the lid are intact and whether the desiccant box closes properly. If the locking mechanisms are damaged, for example a threaded pin has broken off – simply fix it with super glue or, if necessary, print a new box.

Maintenance of the desiccant (silica gel)

Check the color of the silica gel (desiccant) at regular intervals (1-2 weeks) – if the saturation of the silica gel is reached very quickly (less than 4 weeks), the filament box may be leaking.

When saturation is reached (discoloration of the indicator dye) regenerate the silica gel according to its instructions.

Normally, 500g of desiccant (for approx. 100ml water absorption) lasts approx. 3 to 6 months until it is saturated and must be regenerated according to the instructions.

Do not leave silica gel granules open in the room for too long – always store in the closed filament box or a closed plastic bag! Also keep the opening of the filament box to change the filament spool as short as possible, so the desiccant lasts longer without having to be regenerated.
