Outdoor Shed Vent Grill

I made 2 of these to provide some ventilation for the outdoor shed, especially during summer. Made it out of glow in the dark whcih should look neat. Probably will paint it due to UV.
Gap between the bars is 10mm, whcih should prevent birds and such to go inside, but i will sandwitch a finer mesh between the gril and shed to prevent wasps and such from getting inside.
