Grinder card Tray

If you have one of those handy , stainless steel grinder cards, this is for you. Its also useful if you have a standard herb grinder. In the kit, there is a scoop and a standard guitar pick. the trough is shaped to match the contour of the guitar pick and scoop. There is also a cover plate to protect the contents. I prefer PETG so that it doesn't melt in a hot car. Layer hight of .16mm is great to reduce ridges in the trough but .2mm is fine.
