Springer Pusher Tug

This is a collection of parts used on a model Springer pusher tug. The kort nozzle is posted as a separate part on Thingiverse.

The hull and deck of the boat are not 3D printed. The deck and bottom are made of 1/8" plywood. The sides, bow and stern are made of 1/2" plywood. The pdf drawing file shows the overall design with dimensions. The txt file shows the profile of the sides.

The deck is supported by a pair of 1/2" thick cross members located as shown in the drawing. The Post.stl is mounted in the center of the aft cross-member. The forward fenders are attached to studs in the forward cross-member.

The pusher fenders are made of three parts - bump frame, bump cross and bump flex. One bumper cross is printed with a pair of mirror-imaged bumper frames. The bumper flex was printed using a "Flexi-Dually" so the the rigid frame and flexible fender are printed as one piece. However, the flex fender is optional and can be left out if you don't have the dual extruder capability. The mirrored frames fit snuggly on the bumper cross piece. There are holes in the bottom of the frames designed to fit onto studs on a structural cross-member near the bow. the exact location is shown on the pdf drawing.

The helmet super structure is divided into separate .stl files to enable printing without supports. Once printed, the pieces can be glued together using CA glue. A floor for the superstructure can be used to hide and opening into the hull. The roof and walls can be sanded smooth, then painted.

The ladder, life preserver, navigation lights, exhaust pipes, radar and radar supports can be glued onto the sides roof. The anchor light hand rails are made of brass tubing cut and soldered as shown in the picture.

Hope you can use some or all of these pieces.

A separate posting shows gripper arms that can be mounted on the model boat to deliver and retrieve model buoys that are also posted elsewhere.
