Do you have a pair of digital calipers?

Your fillament looks too blob-y and fluid. maybe something is too hot, like your hot end or bed. or maybe you have your firmware set to extrude too much per step.

Buback : Thanks, I will try changing the temperature,
although I have set the values to 230 and 110, but maybe the sensor is not touching the piece of glass.

Thanks

The hollow thin-walled object is more of an advanced test object, so you can try printing an easier test block. I like the 40x40x5 solid block. It's probably the easiest to start with. Once you get the first few solid layers done, you can already see whether the extrusion is too much or too little. (Or whether there are some other problems.)

Well, you need a pair of digital calipers to accurately measure your test objects. But more fundamentally you need them to tell if an x/y/z move was the proper distance.

This way if you tell the x-axis to move 50mm you can measure that it actually went 50mm.
