Out of pots? NP

So these fast ones came out in a day and I wasn't ready for their size. Usually drop them in a peat plug for a little to root. But not these, they are 2 to 3 mm taps. Scramble around for something, came up empty. 

So, design a little pot 150mm by 80 and print it. Only need 3 and it will take about 3 hours.They aren't water tight. And won't be any good after 2 or 3 uses. Put them in recycle bin for pop bottles. Or PET bin.
