I created a separate page for THE QUEST FOR DRY FILAMENT, which has the Sensirion Board, housing, and bracket. It also has the in-spool dessicant holder. Also, our experiments with Adafruit Feathers and the SHT4x Relative Humidity sensor will have resources in that section.
The Bambu X1C Wiper I was talking about. It has been working really well.

Hearing Protection
ISO Tunes Xtra 1.0 Earplug Earbuds - These are in-ear devices with an OSHA-compliant Noise Reduction Rating (NRR). They work great, and are good for a “minimalist” load-out, because they are small.
3M WorkTunes Connect Hearing Protector with Bluetooth Wireless Technology, 24 dB NRR, Hearing Protection Safety Earmuffs, Black - These are my preferred hearing protection in the shop. The Bluetooth works great, and I find them very comfortable. One thing I like is the ability to take them off and put them on easily, and with gloved or dirty hands.

U.S.SOLID 10L Cryogenic Container Liquid Nitrogen LN2 Tank Dewar with Straps 6 Canisters
This is the 10-liter deware I use for liquid nitrogen. It performs very well, and the insulation is excellent.
*** WARNING: Do NOT attempt to use liquid nitrogen without adequate training and safety equipment. It should never be stored in a sealed container (it will explode). It should never be used in an enclosed, un-ventilated space because it may displace oxygen and cause hypoxia (lack of oxygen potentially leading to death). It should never be transported in the passenger compartment of a vehicle. Do NOT attempt to use liquid nitrogen without adequate training and safety equipment. ***
Miereirl 128 Oz Insulated Water Jug, One Gallon Stainless Steel Vacuum Double Walled Water Bottle With Handle, BPA-Free Keep Cold 48H Hot 24H, Wide Mouth For Sports, Traveling, Camping, Stainless
Found this as a candidate for small liquid nitrogen cryo missions. One gallon, stainless. MUST NOT BE SEALED CLOSED WITH LN2! USE WITH LID OFF!
This unit performed fantastically well for an LN2 container with the lid off.
Looking for a bucket for quenching oil in the heat-treating process, I found this:
Vestil 5 Gallon Steel Pail with Handle and UN Rated Lid with Lever Lock, Black
This performed very well as my quench container, and I really like the lid clamp.
Stainless Steel Parts Cleaning Basket, 9-1/2" Diameter x 12" H, Fits 5 gal Bucket (Bucket Included), 304 Stainless Steel Dip-And-Drain Mesh Basket, Swinging Loop Handle
This is for use in the above metal bucket for catching and agitating parts during quench. Not cheap, but effective.
