Do you count spores or colonies on #plates, after spending hours measuring and marking gridlines on the bottoms of #media plates?

If so, consider the following #tool I developed. I call this the #PlateGrate. The design is free, so you only have to pay your printer service. I can print it for about $4-$10 at my local 3D printing service.

Unlike the sticker-based tools available from major suppliers, this tool is #cheap and #reusable.
