Filament Desiccant Holder for Spool

prusaprinters

<p>I have a filament drier, and the vacuum storage containers are brilliant, but expensive. &nbsp; A Freezer grade zip lock bag works well, but still lets a little air infiltration as the seal isn't perfect and the bags can have micro defects. &nbsp;This cup fits in the spool hole and if you use indicator desiccant and print it in clear, you can see the moisture state. &nbsp;I printed it in Taulman Clear PETG.</p><p>The lid snap fits in, and you might need to bend the lid or squeeze the cup to get the last ‘nub’ in. &nbsp;The desiccant I have from McMaster pretty much stays in, but you don't want to store the spools vertically. The cup sits flush so you can stack the spools.</p><p>Clear PETG</p><p>0.2 Layers</p><p>Low (5%) or even no infill for better vision inside.</p>
