I remade my gradiatuon project - Panzerkampfwagen VIII Maus that I modeled all by myself in 2018. It's in real size so you have to scale the STL models down to 2,84% (not open to fit to bed). In that case they will all fit to the 250x250 print area of most of our Bambus. Only chasis must be placed diagonally, scaled down to 2,8% and then back to 2,84%. Most of the parts are superglued together and the tank doesn't have movable tracks but only turret (gun also solid).
