This model covers a standard cube shaped tissue box (allowing space for a 120mm cube) but could be scaled to your desired size. The tissues are pulled through the chimney to replicate the steam/smoke of an engine.
I designed this using the well known 'Benchy' boat model as an inspiration but this is not a remix, all the parts are brand new.
Printing: I would recommend using the 2 files that contain individual parts of the model which can be glued together. They will require some supports but much less that if you printed the object as one piece.
This is a big model and I used about 600g of filament. The model in the images was printed using a 0.4mm nozzle and 0.3mm layer height, with 2 walls and minimal infill.
Please check the size is correct for you before printing this model
