STL Cutouts & Height Adjustment

I have an existing 3D-printable part in STL format that needs a few quick tweaks. The part is a drying rack for a sonicare waterflosser. My goal is to add more cutouts to the part to allow for better air-flow so the flosser and it's parts dries better. I also want to adjust the height of the stand on the right side of the part.
Specifics:

1) Add honeycomb-pattern cut-outs to the areas I will mark on the model. The pattern should look uniform and keep wall thickness consistent. The goal is to add more air-flow to the part, to allow the flosser and the other parts to dry better. If you have suggestions on other areas to add cutouts, I am open to that, but I do not want the shape of the overall part changed. Notes on where I think cutouts can be added: https://share.cleanshot.com/SShqZcGXcxH0ntW6XZWF

2) The cylinder is where the body of the flosser sits, and to help it dry, the top lip of the cylinder should have cutouts. Likely makes sense to be honeycomb to match the cutouts to add airflow.

3) Reduce overall height of the right side cylinder. The height of the cylinder + funnel should be: 3.75"
All other dimensions should stay the same.

Please work directly on the supplied STL, preserve all other geometry, and return a clean, watertight STL ready for slicing.
