Well i will ask a friend to make me those stands in 3D so i can print at home. The price you pay for his 3D printed ventilation stands is way way overpriced. I have a 3D printer, those stands will cost 1 euro to print each. and the silent fans cost around 17euros each.
It's completly overpriced those fan kits.

It's overpriced, point.
Then, everyone is free to do what they want, if they want to buy i think is great for them and for you. I didn't said you where stealing or scamming, just said it's overpriced, and it is of course, specially the kit with the 3 fans.
But sure that will help people and if they are willing to pay everyone benefits from it. What i said was not an insult or hate, was just a fact, and nothing personal i don't know you and i don't judge you, i judge the price that is sold.
For the one saying " and what about the original ideas and design?" Well, he didn't invented the powder... Adding fans to a piece to make it less hot is not that an original idea...
Some weeks ago i bought some new coin doors, and they didn't came with the metal part that turns on/off the coin door switch. I created a 3D piece to solve the problem, i spent some hours on it and i posted the file for free in a facebook pinball group. The same, i didn't invented the powder.
( my initial comment was just about the fact it's overpriced , just that, i will not comment again, you can tell what you want am ok with it )
