Duplo compatible baseplate Volcano Island

This is a Duplo compatible baseplate with an island in the middle, seamlessly extending my sets of river base plate. Bonus: This time, the island can be extended by a volcano.

There are multiple ways of customizing the volcano. Since it comes with a standard knob, you can attach a variety of additional models, such as:

• Small fire: https://www.thingiverse.com/thing:2187993

Major thanks goes to pwl_b, who created the very initial model of a river baseplate. See my other base plates for remix details and credits. Original model: https://www.thingiverse.com/thing:3487787

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).

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.
