Parametric Woodbox Connector

I wanted to make my own custom-size storage-boxes without fiddling around or worrying about timber-joints and wanted to use the least amount of tools possible. This is my first draft of a parametric model to support any size of sheet-strength for my timber and create boxes in exact the size I need.

The model is parametric and you can change variables like timber-strength, screw-diameter, height, wall-thickness and height of the connector and the gap between the edges.

To calculate the exact sizes of your wood sheets based on the outter width and length, I've created a Google-Sheet with a small set of formulars where you can enter your metrics – you can just copy it to your own Google Drive and use it.

I printed it in original Prusament PETG and it is really sturdy – I was even able to stand on the first box I made which is clearly not recommended and definitely off-purpose. I also tried PLA and it also works fine but wont be as stress resistant as PETG.
For the bottom pieces I used support, which is easily removable afterwards (see 3mf files).

Be careful when you fasten the screws, so you won't crack/split it due to the layer-orientation.
