Duplo compatible baseplate with river (90 degree)

This is a Duplo-compatible baseplate with a river in the middle, extending my first base plate model by a 90° curve of the river.

Major thanks goes to pwl_b, who created the original model of this baseplate. See remix link for details, credits and original model. Additional thanks to user_1091264608 for inspiration/request.

Please see all details in the description of my base plate with straight river. For extension idea, just keep in mind the base plate is not square (to fully utilize print bed size). The plate has a size of 15x14 knobs (240x224mm). If you want to go for a 180° turn with two plates, you have to mirror one plate before printing.

P.S. The dimensions of the knobs were calibrated for printing on a Bambu P1S with PETG. It is might not accurate on other printers or with other filaments. I recommend to test with a small print first, esp. because fit can vary with each type of filament.

Please let me know if you have additional requests for enhancement, ideas, or question.

Update: I added more versions of this base plate
