After looking for ages to find a plate rack to print for work in a low resource region and supplies take a month or two to arrive; I finally found the petri dish holder by NormalPeople.
It looked incredible except it was both too big for my printer and too big for UK sized petri dishes. I split down the rack and tried to smooth it out. Its a bit of a Hack job, but it works nicely!
