6.4 mm audio/instrument jack dust plugs

thingiverse

These are 2 versions of a simple 6.4 mm audio jack/instrument dust plugs which you can use to cover up those unused jacks in your equipment. There is a version with a small handle which makes it easier to put in and remove and there is a version without the handle, providing a more 'flush' look and feel if you use them. Print them upside down with supports only touching the build plate.
