Keelcrab Flotation Block

prusaprinters

Keelcrabs (keelcrab.com) have internal round foam blocks that must stay inside during operation.  They're hard to clean and can break off rather easily.These custom parts should provide same or similar level of flotation for your robot while being easier to install and to clean after use.Use 20% infill or less, print out the two halves, glue together after installing them into the crab's belly between two metal brackets.  Six of these blocks (twelve prints) should be enough to provide flotation level similar to what original foam blocks do.My robot came with one 15mm and two 25mm blocks on each side of the robot, six in total.  Four 25mm and four 15mm blocks were included as spares.  These custom designs are meant to replace 25mm blocks, but can change their level of buoyancy based on infill %.
