MPCNC Surround

thingiverse

My first attempt at an MPCNC surround was a success, meeting my goal of adding soundproofing inside while keeping the vacuum internal to cut down on noise and dust. I began by assembling the work platform and posts first, then attached the posts with just one screw so that I could fine-tune the assembly as I built the roof. Next, I secured the legs to the work platform with multiple screws, added the trim pieces, walls, and roof sheeting, and finally assembled the door on the side and hung it with door hinges. I attached the CAD model so that you can easily modify the 2x4s for different sizes. Without a saw, having the CAD model helped me create my Bill of Materials (BoM), and I had the lumber store cut everything to length for me at no extra cost. Wood and screws totaled around $130. UPDATE: To enhance soundproofing, I used multiple layers of old towels on the sides and purchased sound foam for the ceiling and doors where towels were too heavy or hard to hang. Towels are placed under the floor to dampen sound coming off the work platform. With this setup, I can be in the same room as the CnC without any issues, and my neighbors hear nothing. However, I keep a fire extinguisher nearby since I packed the enclosure with so much flammable material.
