I created this strainer for use with my new SLA printer. My hope is that the resin wont stick to much to pla. May try this with PETG if not.
UPDATE: It works perfectly with PLA! rinse with alcohol and water after each use to keep the pours open.
Create a ring, build an arc profile on a bisecting plane and then revolve it around the center axis.
Drill a row of 2 mm holes in a straight line and circular pattern it 12 times to create the even mesh.
