My version...this one is for 2 of the smaller 32oz bottles, which we refer to in my area as a Howler.
No glue or nails, used the dowels to tighten it up. It is very solid.
It took a few test cuts to get everything to fit right. Used an Onsrud 1/8" compression bit at 80ipm/30ipm and ramped into all cuts. I could have went faster with no issues. Clean cuts, only had to sand down the tabs.
It is 13" x 12" x 5".
