I just finished making a bubble box out of legos, and different micron nylon screens. they are 150u, 105u, 73u...took me like a while to make this thing. it has a swivel on it so i can turn the screens sideways to look at my kief and a locking mechanism to keep it as a whole and all the screens can separated if needed to scrape. i thought i would share it with fmb. i have just started using it and it awesome dimensions are:
5.5 inches tall (14cm)
4.5 inches width (11.25cm)
4.5 inches depth (11.25cm)
here are some pics of it
