This is me new rack I built out of 5/8 OSB with 5 coats of polyurethane on it...

wood was $30
polyurethane $15 for a gallon
screws $5
hardboard $10


Yes I know I need a backup thermostat, I have one on the way and will wire it in but here it is... I also did some calculations wrong and i can put another shelf on top, Im going to do this in the near future
