Hello Everyone. Here is a handy filter to remove dust and debris before it enters your extruder. -- This was adapted from CreativeTools, thing:52203 -- Brilliant! I enjoyed his design so much but needed a quick way to get to the sponge inside without tools as I battle dust often. So, I offer this adaptation. Included is the STL file ready to print and I have put in the STEP files and Invite everyone to adapt this to their needs. Let me know of your improvements.
