Tree protection / Plantskydd

Put them high or else the plant will have a bite.PLA lasts only one season so I recommend PETG.Print has been made from Openscad and can be modified by you. Two examples has been added. I use mostly 95mm.https://openscad.org/ It is time consuming to print but you print them for around 1/10 of the cost of buying them. Fill your bed and start to print early in the season so you have a lot in the end of the season.
