Corner connectors for using ½ pvc pipe to create grow tent side supports. Will help with air pressure sucking in sides of tent. Also including a net clip for use to stretch trellis netting. Ive printed and used the 22mm pole version, but do not have a 19mm,18mm or 16mm pole to test those.  Feedback on fit is welcomed. Print the corners using tree support. I used PLA with no issues.
