Two L-brackets with magnets glued to them, wrapped in electrical tape to help with adhesion to the freezer. Velcro attaches the drip tray to the brackets. Holds 3 full pints with no issues and I can take it off easily.
I can be lazy at times, but I've always had the mindset of doing something right the first time rather than half-asked. I'm passionate about brewing and I want a quality product. Doing a double brew day can be fun when you care.
