Steampunk trains automatons and platform set of 3D print model

Lovely models, sadly the trains are so large that they are virtually unusable. I have tried to slice the models into say four pieces but just cant find an easy way to do it. Whilst it is said that a 300 x 300 would do it wont, the models are far bigger - i have some of the bigger printers such as the JG MAKER - 320x320. Likewise if the models had been split then you could have printed without supports - the openlock doesnt refer to the trains it refers to the platform pieces. Would love the author to slice the trains and fit the openlock into it. Live in hopes.

Les fichiers pour les rails ne sont pas finis, les fichier pour les trains ne sont pas optimisé pour l'impression 3D...je regrette mon achat ..
