Microphone Shield

I have created these parts to make an acoustic shield for my microphone.
Similar productions are expensive. But with this, you only need to buy 2 sheets of 30x30 cm foam. 12 sheets on eBay cost you $20. You only need 2 of them though.
You cannot find the original less than $50 while there are items with a $400 price tag. this original one will be attached to the stand, while my design has two solutions to be attached to the rod that also microphone is attached to or can be directly stuck to the microphone itself.
I preferred the first solution because even though all the set is not that much heavy but maybe there might be some vibration can be transferred to the microphone.
You can find images of the second solution assemble, and also the first solution in the attached photos.
Please let me know what you think.
