rain barrel cover clamp

thingiverse

The cover of my rain water barrel was alway flying away when it was windy so I designed this clamp. It fits onto the square 203l barrel from garantia. I think "graf" has the same design and the 300l or round versions could work also. As it needs just a little force to prevent it from flying away I use just one clamp which is quite loose and easy to remove and also allowes to open the lid without removing the clamp.
