Secondary glazing clip

thingiverse

Simple clip for secondary glazing using 4mm glass with a 3mm thick closed-cell foam sealing strip stuck to the edges of the glass. The clip compresses the sealing strip a little and allows for some uneveness in the surface of the window frame to which the glazing is attached. Working with glass can be dangerous! Take appropriate precautions or of coure you can always use synthetic glazing which is safer to handle but can be tricky to cut!
