Cat Feeding Platform - Part 2 revised

I printed the fabulous Cat Feeding Platform from JimmerJammer. Unfortunately Part 2 did not want to slice well. The model seemed to be unclosed and needed repair. When repairing it got closed at the top. So it would have no opening at all...

Therefore I revised part 2. I imported the STL-File to openscad and sliced the top part, then rebuilt it using openscad cylinders.

This revised version works for me.
