Good evening, I wanted to know if anyone has an STL file of a lego pneumatic piston! thank you

You want an STL file for a Lego pneumatic piston? Is there any particular reason for wanting one? Also, I don't think you'd be finding it here. Either check the Digital tools forum on this site, or maybe a CAD specific forum, which may give you better luck.

is a pneumatico Lego, for a print 3D

Why don't you just get a Lego pneumatic cylinder?

You can ask efferman, he's been making all sorts of STL files.

The surfaces on 3d printing are not smooth enough to get proper working pneumatics.

for the intentions that I have not just the simple lego pneumatic, I am doing a dump of volvo 6x6 and I wanted to put the cylinders long as the real ones, but since the lego not produced them and I tried to ask a friend of mine has a printer 3D and told me he would not trouble me cylinders as I wish, however, asked me a STL file of a cylinder lego, no matter if you can not help me thank you very much

There is that. It's not lego but it's a start

I will 3d print that sometime next month and see what it is like

Jaaptechnic has some pictures on his Flickr gallery of extended pneumatic cylinders that he made from scratch. It would appear that he took the seals and stuff from a standard Lego cylinder, and attached a new inner and outer shaft.

And, as a bonus, he is using them for the exact purpose you are, as the lifting rams on a Volvo dumper.
