Metal Pails for Storage

These are being evaluated and are not great for storing filament… see pouches below.

Metalized Pouches for Storage

THIS is the way to store filament! —> 20 Mylar Bags for Food Storage, 2.5 Gallon Capacity, Extra Thick 15 Mil — https://amzn.to/4hjzM7G

Data is presently being collected, but these are kicking butt!!

A paper entitled “Water Vapor Permeation in Plastics” is an eye-opening read related to the storage of filament. A worthy read!

Measurement of Humidity

Here is a hygrometer you can use as a reference standard in your operations… it costs around $30. It is an eval board for the Sensirion SHT 40 sensor. VERY good performance, extremely fast response time, accurate to 1.8% error, and useful down to 0% RH. Really.

At DigiKey, Part Number 1649-SHT4XSMARTGADGET-ND. https://www.digikey.com/en/products/detail/sensirion-ag/SHT4X-SMART-GADGET/14318392

I sell these in the store!

(I am also playing with the Adafruit Feathers, and a Sensirion SHT45 as an attached sensor. More on this to come…)

A fast-change Bambu Spool Dessicant Cartridge…

Click HERE for the 3MF file for the Bambu Spool Dessicant Cartridge.

(Please note that this is a REMIX of a design by EnRiON, from the Printables.com site. Linked HERE.)

Spencer scaled up the original design from a 50mm diameter to a close fit (55mm) for the Bambu Reusable Spool. Importantly, the flange on the screw-in cap was removed and replaced with two snap-in features calibrated for the width of the Bambu Reusable Spool.

This is the indicating dessicant (silica gel) which we use and re-use: https://amzn.to/43MiQih
