Hi everybody.
I have a Probotix Fireball V90 cnc and as i live in an apartment along with others i want to be nice to my neighbors and my girlfriend.

So i decided on building a wooden box with insulation for it to collect dust, and remove some of the noise.

Here is how i did it.

18mm Mdf plates cut into 95cm x 95cm sizes. Put together a box with it.
Cut the front plate in 2 to create a door.

Put in 30mm thick car insulation sound mats from our local Biltema.no in norway. They are made for insulating cars and boats and such and comes with adhesive stickers on the back.

Added some hinges for the door, and a hole for cables.

I have not meassured excactly how much noise it removes but i will guess about half of the noise from the dremel on 30.000 rpm , and about half of the stepper noise. Very pleased with this build so far. Next thing is to fly the machine on large rubber straps to remove vibration!

I ended up using all 8 1m x50cm isolation mats and i still need more in the back but that will come later ;)
I guess this removes about 30-35db of noise in total. I bet more goes when i remove some of the vibrations. Very happy with this build so far.

Got the Mdf for free from a friend, so the only cost so far was the isolation mats that cost 159NOKR pr 1mx0,5m x 8
And the hinges for the door :)
