Model based on request from Jake Mosher in the Facebook Timemore Sculptor Grinder User Group. Alternative to the metal blind shaker distribution tool introduced by Weber and copied by several other companies/websites like aliexpress.
Press the cone onto the mouth of the shaker cup. Use the lid to ensure flush alignment.
Designed to sit on a 58mm portafilter. Additional revision created for 51mm baskets. Message me with outer diameter of other basket rims if you would like those versions.
