S⁴ (Strong Seed Sieve Stack lowtech)

prusaprinters

<h3>TL;DR</h3><p>Strong garden sieves to separate seeds by size. The sieves can be stacked. Start with wider ones on top and tighter ones down the stack.</p><p>&nbsp;</p><h3>How to use?</h3><p>Stack the sieves with the wider one on top and the tighter ones down wards to separate seeds by size. Each sieve will hold the seeds to big to go trough the mesh of this sieve.</p><p>&nbsp;</p><h3>Printers</h3><p>The diameter is 180 mm, that's big enough and could still be printed on the prusa mini.&nbsp;</p><p>&nbsp;</p><h3>Size / Scaling</h3><p>You can scale the sieves to any size you need. You could scale XY freely, scaling the Z axis may cause problems with the thickness of the bottom.</p><p>&nbsp;</p><h3>Filament</h3><p>I used PETG but many other filaments will do the job too.</p><p>&nbsp;</p><h3>Magic</h3><p>The mesh of the sieve is not made with CAD (freecad) but with the slicer. The whole sieve is a single rotated sketch.</p><figure class="image"><img src="https://media.printables.com/media/prints/279727/rich_content/d492ae2f-3c59-4375-9e76-e6981f39132e/sketch.png#%7B%22uuid%22%3A%22243a2bf4-b17e-4cfb-a510-6e76c0663419%22%2C%22w%22%3A1832%2C%22h%22%3A1102%7D"></figure><p><i>sketch - the thickness of the sieve get lower with lower mesh sizes.

If you print with lower extrusion wide you may go higher but the mesh wide with 50% was the smallest we need. I added all models up to 90% infill so do what you like to do.</p>
