Introduction

After doing hundreds of 3D prints for canopies, skids, shields, et., I decided to build my own Vacuum Forming box so I could get the weight dramatically down on some these parts. I did a pile of research and found many different styles and sizes but finally decided to simply take the things I liked in many pictures found on google and design my own. This then is my version.

Tools I Used

Besides the basic hand tools, these power tools helped immensly with keeping things sized and squared perfectly.

1. 10" Chop saw w/60 tooth carbide blade

2. Drill press

3. 10" Table saw

Parts & Pieces

Here is the complete parts list for this project. All dimensions and screw specs for this project are imperial (inches). The dimensions for the wood cut pieces are based on perfectly sized wood so if you copy this you will need to make adjustments based on the wood you select.

The Build

First Things First

Toaster Oven

While reading many articles on how to create an effective heating element I found a YouTube video from a guy who was simply using a toaster oven to heat the plastic in an aluminum frame. So, I bought a toaster oven at Wallmart for $19 and gave this method a try. I found that these heating elements provided more than enough heat for this purpose so I incorporated the heat elements and the complete oven control system in my design.
