I made these Dinos from plans that I found around the internet. I cleaned up and modified the files to cut on 1/8 plywood. I’ve included the SVG and DXF files for all of the Dinos.
I Made the tolerances for a tight fit. I found a nice hammer to tap the pieces in place here http://cartonus.com/hammer/
You shouldn’t need any glue. If there any loose fits, I found this glue works great. It is very thin and sets within seconds. https://www.amazon.com/gp/product/B002FORR2I/ref=ox_sc_act_title_1?
