This downloadable dxf file will allow you to cut the puzzle pieces for your own 48" tall T-Rex dinosaur. The file is set up to cut 1/2" thick material with 1/2" slots.
Full Size - 48" tall T-Rex - slots are for 1/2" thick material
Half Size - 24" tall T-Rex - slots are for 1/4" thick material
By changing the scale of the file to match the thickness of the material you are using you will be able to cut dinosaurs in different sizes out of different materials.
For instance you can take the file for the 48" tall T-Rex for 1/2" thick material and then scale it to half size to cut a 24" tall T-Rex out of 1/4" material.
You need to cut the puzzle pieces to the correct scale so that the width of the slots match the thickness of the material you are using.
If you are cutting 1/2" thick material you will need to use a 1/4" diameter or smaller bit.
If you are cutting 1/4" thick material you will need to use a 1/8" diameter or smaller bit.
