Shower Tray Insert for Ikea Voxnan

This is a tray insert for the Ikea shower tray Voxnan.
Convenient for smaller items.
My razor and the small shampoo tubes my kids like so much fall through.

This design has a large STL because I used a high fragment number $fn.
So any rendering has a flawless result.

NB: When editing input small $fn values.
Before opening the SCAD: It it a very calculation intensive design!
