Dessicant Container - Fits in Filament Spool. Includes hygrometer lid, vented lid, funnel.

I put these in filament spools that are stored in my filament storage bins. (I use Ezy Storage 18L/19Qt Waterproof Clear Latch Totes, which hold 5 spools, are stackable, and seal well with silicone grease applied to the gasket.)

These dessicant containers save space, eliminate the mess of dessicant packets, and allow viewing the humidity level without opening the bin.

I keep one of these in the Bambu AMS also. It keeps the humidity around 10%.

Key Features: 

Unique double wall design provides a very large increase in ventilation surface area, allowing air flow along the spool axis (not blocked by the spool wall) as well as the end caps. This keeps the humidity low.

Low profile lid, so that you can leave it installed on the spool during storage, and on printers that don't require the spool opening (e.g. Bambu AMS). Protrudes out beyond spool only 2 mm. 

Includes Hygrometer compatible threaded lid. Hygrometer snaps into the lid. 

Includes funnel that screws onto the container for filling dessicant. 

Specifications

Compatible with spool inner diameter of 55 mm (will fit 54.8+ mm). Larger sizes are supported by using a bushing. Contact me if there is a size you need. 

For filament spools with an inner diameter of less than 55 mm (e.g. CC3D filament), use my smaller diameter version. However, the smaller diameter does not support the hygrometer lid. 

Use with industry standard 3-5 mm diameter bulk dessicant. Ventilation openings are 2.0 mm. I use Dry & Dry Premium Orange Indicating Silica Gel Desiccant Beads Rechargeable Silica Beads. Amazon ASIN B0CM7Q3F9D.

Container holds appx 73 g / 2.58 oz of dessicant. 

There are 2 Container types provided: 1) open on one end, 2) open on each end. You can use the dual threaded model to lock the container onto a spool. Each has female threads.

Print recommendations: 

Designed for PETG. There are tolerances on the threads, so make sure your filament is good quality and dry. 

I use 10-15% infill, 3-4 wall loops (for threads). 

All items are designed to be printed without supports. 

Container - print standing up.
