Dutch Drawbridge
This model of a (Dutch) Amsterdam Canalbridge is based on the drawbridges in Amsterdam and is part of the “New Amsterdam Crochet Project”, that my wife has initiated.
Many more 3D printed models were the result of this project. I have included a few pictures of the entire New Amsterdam crochet scene (by night), to get an idea of the project this model is part of.
When fully assembled this drawbridge model will be 25 cm long, 22 cm wide, 19 cm high.
This bridge fits well into the LGB model train scale (approx. 1:25).NOTE: All parts can be printed without the use of support material.Parts list -> number of times to print:
BRIDGE_MAIN_TRUSS.STL-> 1 piece
FLOOR.STL-> 1 piece
BRIDGE_CROWN.STL-> 1 piece
BRIDGE_ARM+COUNTERWEIGHT.STL-> 1 piece
BRIDGE_RAMP.STL -> 1 piece
RAILING_BRACE.STL-> 2 pieces
FENCE_RIGHT.STL-> 1 piece
FENCE_LEFT.STL-> 1 pieces
RAILING.STL -> 4 pieces
Additional materials:
M3x10 bolt: 4 pieces - Used as hinges - connecting the 2 rail-braces to the 4 railings
M3x10 bolt: 4 pieces - Used as hinges - connecting the 2 rails with the main truss
M3x25 bolt: 2 pieces - Used as hinges - connecting the floor part with the ramp part
M3x20 bolt: 2 pieces - Used as hinges - connecting the arm part to the “crown” part 2
Miniature metal chain (as used in jewelry) – to hang the floor (road) part onto the arm
part. Also, another piece of this chain has been used to pull down the counterweight (and thus raise the bridge).
Happy printing!
