Seed Sprouting Tray

thingiverse

I plan to use this for nurturing small quantities of cat grass (also known as Wheatgrass) for my feline companion. The standard diameter is 84mm by 15mm high.\r\nIt's parametric, so you can easily modify the diameter, height, hole size, hole spacing, and other settings using Customizer to suit your needs.\r\n\r\nThere's also a "basin" piece that fits underneath to hold water. My test print seems to be holding water so far, but if your printer tends to produce slightly loose prints, you may need to apply a waterproof coating (spraying with lacquer might work). To create the basin, simply set "basin" to 1 in Customizer. The code adjusts the size to fit the tray without altering the settings. You could also adjust the wall thickness and bottom thickness to make it more rigid and possibly watertight. The inner diameter of the basin is 2mm larger than the outer_diameter variable for a loose nesting fit.\r\n\r\nThe default wall thickness is very thin, aiming to minimize filament usage. Changing the wall thickness to 2mm will make it relatively robust. If you modify the wall thickness, it's advisable to change the bottom thickness as well.\r\n\r\n[update 3/14/2020] A correction was made to the basin code, and a thicker walled basin STL has been uploaded.
