This is a 140 mesh Tyler sieve. It drops into the plastic 3D printed collars and fits tightly. And the collars also need to mount tight on the pipe so everything stays secure during vibration. The collars were printed, upside down, in 110 degree sections. I created the design using Fusion 360 by drawing the cross-section profile and then dimensioning and revolving it. Typically creating these is try-adjust-print-again process to get a good fit. Remember never to wash these printed parts in hot water or they will warp.
Making your own sieve shaker
All you need is an inexpensive vibration motor from Amazon, a five gallon pail, some metal and welding and 3D-printed collars to hold the sieve in place.
