Number 2 in my designs of planter trays to solve the house issue of plants without planter trays. This one is slightly smaller than my first one (approx. 5.8in at base and 7.5 in at top) and I have added 0.5mm raised tray design to kepp the plant pot raised ever so slightly for better water movement in the tray.

I have provided the 3mf with settings I would use but since I have the A1 the printer is powered off till I receive my replacement heat bed as part of recall. STL is also included and is what I used via Cura to test the print out as I had to print it on my only other printer which is a Monoprice MP Mini v2 so I had to shrink it down to 58% size to fit on that bed. Pics are from the completed print using Sunlu PLA+ Gold. Measurements in pics are from the 58% sizing.
