About this 3D model
I made a bigger base which fits nicely on a 30 x 30 cm printers build plate. The base thickness is 1.5 mm so 5 solid layers with 0.25 height. Reference measures are from here https://www.thingiverse.com/thing:615256 Designed in Fusion 360. Before printing, this big plate consider making a test print of this https://www.myminifactory.com/object/3d-print-42646 for making slicer adjustments. To get a nice fit of a brick I play with extrusion multiplier.
