Round Coffee table, snap-fit assembly

Hello All! PLEASE READ THE DESCRIPTION CAREFULLY TO AVOID ANY MISUNDERSTANDING AND DISAPPOINTMENTS! This is my first large project created in fusion 360. It has been through a number of iterations, this is the latest and greatest so far. This is a LARGE print, that requires precise fitting of notches to avoid structural instability. Print times are long and it takes about 2kg of filament. Here are some important things to take into account before printing. BEFORE printing the whole model please take the time and patience to print the test pieces on plate 8 and check how they fit together as shown in the pictures. A good tight fit is necessary if you do not want to glue the pieces together. Thread tolerances are quite loose and should be ok. Warping must be minimized at all costs. Please use dry and good quality filament and a clean print plate. If you are using an enclosed printer like the P1s turn off or reduce the speed of the auxillary cooling fan and keep the top and/or front door
