M-1J1R Filament Storage Box Kit

The M-1J1R filament storage box kit contains all necessary components for building a storage box or for mounting to an AMS/MMS and fits our 3D-printable models for membrane mounting to the inside (Printables or Makerworld) or outside (Printables oder Makerworld).

Scope of Delivery

• 1x Rosahl M-1J1R Dehumidifier Membrane incl. gasket
• 1x VREG-2 USB-C Power Supply Module 3V/3A
• suitable flat plugs (4.8mm/6.3mm) for crimp or solder
• suitable sealing o-ring for USB-C-VREG2 cable feed-through (inside mounting) or the membrane (outside mounting), not shown above
• set of suitable M3 screws, nuts, washers

Which Membrane Suits What Application?

The following table reflects our own applications with different membranes and usage scenarios in our climate zone with max. 65-70%RH and could serve as a guide for membrane selection.

(1) This is the specified applicable volume by the manufacturer. For 3D print filament storage at low humidity levels around 15%, we recommend to oversize the membrane at least by a factor of 5 or 6. Achievable end-humidity depends on various factors like box sealing, temperatur, outside humidity level. In regions with high air humidity it might be beneficial to oversize the membrane more.

(2) The Bambu Lab AMS comes with some manufacturing variations and can be less properly sealed as stated. Given this, also an M-1J1R or M-2J1R can give decent results but it is recommended to carefully check for potential leakages and proper/tight gasket sealing before chosing a membrane size. It might hence be beneficial to oversize the membrane more. If in doubt, contact us prior to selecting/ordering.
