Toys for boys. Old boys use computers, small boys need other toys Here is next thing in river serie - nice push tug with bowthruster and extendable bridge inspired by project from attached photo. Size 225x100x(30-shell/30-deck) All these designs in reality must operate in shallow water and pass under bridge or cables - limits from bottom and top. And handling a bunch of 50 barges by one tug (like on attached photo) require high power engine and profesional skippers. bridge in extended position must be secured by pin. Catwalks should be fenced - print few rails, cut required length and glue. And do not forget print LSA (Life Saving Appliances) Bridge window frame added. Added simple crane (rotate,raise)+ ERtop with crane base & post Coded in Template Shapes_Text //https://www.thingiverse.com/thing:4863092 (OpenSCAD CSV). No code this time - I tried to make it extendable, but I missed something. Anyway result is good enough to publish. Enjoy! Edited 19.10.22 - improved code added - see remix Edited 31.10.22 - rim-driven thruster+code added - see remix
