All the parts are sized to print on a 200mm-class printer like an Ender 3. All parts should print without support except the top level of the tower, as it requires an insane amount of tree supports. I've included my gcode file for that segment so you can see what I mean. Use brims as needed. The tower sections stack on four 3/8 inch wooden dowels. I used super glue to join the tower parts… just make sure you don't glue one upside down. The top grid sections will have to be trimmed to fit against the top level of the tower. Refer to the original model by herbys on Thingiverse (which is amazing btw) https://www.thingiverse.com/thing:5403074 for more instructions and the rest of the design. The other parts can be printed on FDM, but it takes some creativity. For example I printed the chopsticks whole, upside down, lowered into the print bed in software until it had enough surface contact to adhere to the bed.
The author remixed this model.
The original model was designed for resin printing, meaning many parts were too thin (think one extrusion width) to print well. Also the parts needed to be altered to print support free when possible. The base for the tower was designed by me, as the original designer built his out of wood. I also designed the pipes and elevator shaft.
