Quite amazing how much air this is moving! No need to buy an extra dust blower or canned air.
Just modified it slightly, added 4 slits so it can stretch a little better when there's just half a mm missing, also added 4 spacers (or however those would be called) to lower the friction when you want to actually remove it again.
Printed in PETG (flexes better than PLA) and it's fitting absolutely great, spot on!
To the original creator: great idea!
