Hourglass

I made this model with the help of the fusion360 python api and made some manual adjustments.  The model prints without supports, but needs good cooling.

I printed it in transparent PETG. I used lightning infill with gyroid infill in the middle of the model.

The python script can be found inside of the zip folder, if you want to make adjustments. I used cylindrical coordinates to calculate the position of each sphere.
