I modeled it in inventor 2021 and added the .ipt file for further adjustments if needed.
For strenght I printed it in PETG at a relative high temperature (250C). PLA works as well but I recommend to increase the layerheight to 0.3 and 4-5 perimeters.
support is needed for the inside see image for reference.
