Dutch Drawbridge

thingiverse

<h1>Dutch Drawbridge</h1> This model of a (Dutch) Amsterdam Canalbridge is based on the drawbridges in Amsterdam and is part of the <i>“New Amsterdam Crochet Project”</i>, 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). </br> <b>NOTE: </b>All parts can be printed without the use of support material. </br></br> <b>Parts list -> number of times to print:</b> </br> 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 </br> <b>Additional materials: </b> </br> 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 </br> 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). </br> <hr> Happy printing!</br> Huib Schippers (Tinkerman)
