90 mm Petri dish holder

Needed an easy way to stack and retrieve the Petri dishes inside an Aldi fermenter which I planned on using as an incubator. worked a treat. Printed the main body in Prusament PETG Galaxy Black and the feet were printed in Filatech Filaflex 40. Used a dab of cyanoacrylate glue to secure the feet in place an after 24 hours at 37℃ everything survived. The short holder holds my spare agar dishes in the fridge and the 150 mm one is better suited for the “incubator”.
