I built a Lowrider a few months ago and realized that the amount of dust that it releases is absurd (especially with MDF). While I am fixing the dust collection system, I decided to make a enclosure that prevents any sawdust from leaving. I did a few test cuts with this and found it extremely successful for keeping the dust confined to within the enclosure and the ground below the machine. As a high school student, my budget was quite limited for the project and I wanted to make it as cheap as possible, so I used Fusion 360 to model a enclosure that was 3D printed and used PVC pipes, PVC fittings, and plastic sheets (the ones typically used for painting). For about ~$75, I created this enclosure and I made it open-source!
If anyone is interested in remixing/adapting the design for their own CNC, go ahead! I’ve published .step, .stl, ,f3d, etc. to make it as easy as possible. Here is the thingiverse number… thing:4905685.
Let me know if you have any suggestions or feedback!
