Customisable Sifter

I Made This Sifter To Change Hole Size On The Fly I Used It To Separate Gravel From Larger Stones In My Aquarium And It Worked Like A Charm. To Customize The Hole Size, You'll Need Blender Or Something Similar: Open Up Filter.blend In Blender, Select The Mesh Area, And Scale It Down Until You Get The Hole Size You Want. The Hole Size Will Only Show What Intersects With The Object 'Circle' On The 'Intersection' Collection, Thanks To The Boolean Modifier. Notes: Filter_applied.blend Is Just Like Filter, But With Modifiers Already Applied. You Can't Scale It Or Change The Hole Size In This Version. If You Need Stl Output, Run Filter.stl Through The Netfab Stl Fixer Tool At https://service.netfabb.com/. I Don't Know Of A Better Way To Fix Stl Files For Slicing. When Modifying The Mesh, Make Sure It Lines Up With The Bottom Of The Outer Ring. Both Objects Have Their Origins Set To The Lower-Most Z-Vertex, So They Should Just Read '0' On The Z Position. This Is Important Because If The Printer Adds Strange Or Small Supports In A Grid Pattern, It Will Be A Mess. Printing: To Get Good Results, Try Pushing Your Print Head's Z-Spacing As Close To Possible For The First Layer. This Way, When You're Printing The First Layers Of The Grid Pattern, They Won't Get Messed Up. I Had This Problem A Couple Times, But I Fixed It By Ensuring That The STL File's Bottom Layer Is All The Same Z, And Then Adjusting My Print Settings As Follows: Extrusion Multiplier To 1.01 At Temperature 215, Heatbed Temp To 70.
