Magnetic Stir Bar
Description
Hey, so it turns out PLA can survive a trip through a pressure cooker at 15 psi. Are you thinking what I'm thinking? Just add a length of 1/8" (3.18 mm) music wire and seal with temperature tolerant silicone sealant or gasket maker, and you have yourself a stir bar for a DIY magnetic stir plate. I use these for home mushroom cultivation. So far, I haven't seen any inhibition of mycelium growth or spore germination.
