Seed tray 9 pot

Friend at work wanted some reasonable sized reusable seed trays to print on his A1 mini so I modelled 9 pot seed tray (I have also done a 4 pot system), 148mm x 148mm square, each pot is 40mm x 40mm at the top and 50mm deep. Drain hole is 15mm. these are similar in shape to the Charles Dowding. If anyone wants a different size/quantity let me know and I will change to model to accommodate the changes and put a new model up.
