Does your flower pot lean? Want it leveled? Make a wedge that fits your garden. take the lowest point to the highest point of the bottom diameter. 3 wedges will be created a) put a wood bar on the top of the pot, touching the highest point at the rim b) put a spirit level on the wood of the highest point/rim and the lowest point. c) lift the spirit level, until level, the resting point should be highest of the pot d) measure the gap, at the diameter distance away from the resting point of the highest point down to the wood bar The wedge should have a good depth to the pot rim rests on it. The width give stability against wobbling. It can prevent slipping off of the pot. Decide on width of the edge and it's height. The slicer software allowed to split the stl, need to fit them onto a normal sized printer. I suggest to print the wedges on the side, give good surfaces, support not needed, and also the force lines align to edge, so they aren't easily delaminated. Printing it upside down, gives nicer the wedge a nicer bottom, and is still rough enough not to slip. Note: if printed with edge, an upside down print requires good gap spanning, support material is difficult to remove. So I printed it without support. 30% infill will support very heavy item, 20% infills worked good for 60 cm high pot filled with soil.
