A remix of the Roborock Docking Station ( https://www.thingiverse.com/thing:4068292 )This was split into 4 parts to fit on my CR10s Pro Bed. 20% infill should be fine.

I've added alignment pegs and holes to the 4 pieces, but beware, even on normal setting, this took approx 18 hours for each of the 4 pieces.

Hope this works for you too

There are some photos of my completed product, however I would recommend gluing and filling the seam lines as this is where water could potentially leak through to the floor
