====== 3D Printing ====== ===== Filament Humidity Monitoring ===== I store my filament in a sealed tote with a dehumidifier : [[https://www.amazon.com/dp/B000H0XFCS?psc=1&ref=ppx_yo2ov_dt_b_product_details|Eva-dry E-333 Renewable dehumidifier]]. I monitor the humidity levels in the tote to keep it below 20% relative humidity. This embedded system [[Filament Humidity Monitor|Filament Humidity Monitor]] is used to monitor humidity levels, display them locally and alarm if either a trend projects passing a threshold or the threshold is actually passed.
