All paid plans come with inch and millimeter units for all dimensions.

Plans are delivered electronically via email download immediately after checkout

The 3D models will be delivered in a .zip format. You will need to unzip the folder first. There will be 3 formats of the same model in for different modeling software. You can open the .f3d using Fusion 360 or the .SKP file using Sketchup. I recommend Fusion 360 since it is free.

There is no cost of shipping for plans since they are delivered via email. Shipping for all physical products is calculated on the checkout page

3D models allow you to save time and easily make changes to a design whether you are trying to fit your build to a specific tool or into a certain sized space
