This is a wedge that is pushed in between the glas windows and aluminium bars and profiles on gardening houses.
The tip is 8mm high and 12.5 at its highest.
The wedge is printed in Medium TPU with 3 wall and 10% Gyroid infill. This will make for only 2 grams per wedge, which makes printing fast and durable.
Be sure not to create excessive pressure with the wedge, as the glass may break during winds and when the house frame moves.
