RIGOL DS 1xxx serie Side noise killer

RIGOL oscilloscopes are good but they are also noisy.
You can change the fan but you have the disassemble the body.
This part just fit the side of the oscilloscope and send the wind to the back instead of the side.
There is 'less" noise.
I fixed it with some 3M Blenderm tape, so I can remove it without problem.
You can also still plug some synchro cable if you need.

I Made it with PET-G, but PLA is good also.

I give you also the FUSION 360 3D file if you want to remix it.
