Modular Filament Dryer for AMS Lite, Fully Printable on Bambulab A1 Mini!

Keep your filament dry while printing with this modular, passively-dried enclosure designed specifically for the front spool holders of the Bambulab AMS Lite. And most importantly… It's fully printable on the A1 Mini! Build it yourself.

What makes it different?

Most AMS Lite filament dryers on MakerWorld either don't fit the A1 Mini's build plate or are unnecessarily complex. This one is designed from the ground up to be fully printable on the A1 Mini, modular (each dryer is independent), and easy to maintain.

✅ Compatible with spools up to ø20 cm (virtually universal)
✅ Tested with SUNLU, BambuLab, DEEPLEE, ELEGOO spools
✅ Integrated XF001 thermohygrometer slot for real-time humidity monitoring
✅ Plexiglass windows to inspect the filament without opening
✅ Tool-free spool swap and filament jam access

Measured Performance

Please take a look at the included guide!

Tested in Emilia Romagna (notoriously humid ~52% RH ambient):

Version	Min RH reached	Plateau duration
Not glued	~39% RH (–13%)	~1 day
Sealed (epoxy + tape)	~32% RH (–20%)	~4 days

Recommended silica gel replacement: weekly (sealed) or twice a week (standard).

⚠️ Not intended for long-term storage of moisture-sensitive filaments. Suitable for passive drying of PLA, PETG, and similar materials during printing. It was developed to make sure we could print PVA without damaging the whole spool to then put it back for long term storage into vacuum dry-bags.

Print Settings

All parts were printed on a Bambulab A1 Mini. Total print time per dryer: ~16h 37m / ~480g.

Parts	Material	Notes
Structural parts (Body, Lid sections)	PLA Basic	Any color.
Clips (Body Side Clip, Base Clip, Lid Clip, Lid Triang. Clip)	PLA Tough	Higher stress resistance and flexibility for snap-fit joints

Standard 0.16mm layer height. Print profile for A1 mini included.

Assembly and mainteinance

💡 Please take a look at the included guide!

IMPORTANT! update to the guide:

To better seal the filament port, please apply teflon tape as shown in the image

NOTE! WE HAVE ALSO INCLUDED A NO-HOLE VERSION IF YOU DON'T WANT TO BUY THE PLEXIGLASS WINDOWS!

Project Status

Currently the two front dryers are complete and working. Back dryers, TPU gaskets, a better filament port and an improved silica container are planned.
