Silica Gel Screw Cartridge for Reusable Spools (Width & Diameter adj ACE compatible)

This model is a screw-in silica gel container designed as a replacement/upgrade for the original spool screw used on ACE / Kobra S1 compatible reusable spools.

Once installed, it allows you to place silica gel granules inside the spool, helping to keep filament dry and reducing issues caused by humidity such as stringing, bubbling, and poor layer adhesion.

Features

• Screw-in design compatible with the Reusable Spool Width & Diameter Adjustable – ACE compatible
• Internal chamber for standard silica gel beads
• Perforated cap to allow air circulation while retaining the granules
• Easy to print, no supports required
• Fully reusable: simply unscrew to refill or replace the silica gel

This simple addition turns your reusable spool into a more advanced filament storage system, ideal for humid environments or long-term filament use.
