A puzzle in 33 parts! No glue needed. Original design by Nicolas Erre <a href="https://3dwarehouse.sketchup.com/model/8f234b9aa29dd3ccf13253d0ba52c6/Wooden-toy-train">https://3dwarehouse.sketchup.com/model/8f234b9aa29dd3ccf13253d0ba52c6/Wooden-toy-train</a> Converted from the DAE file to SVG using openSCAD and inkscape. Adjusted sizes for 3mm plywood, all the slots are 3.1mm wide. Improved assembly of the wheels. Added a support for the loose end of the wheel cover. The dimensions are 27 x 13 x 9 cm A scale N version (1:160, 9mm gauge) is also included, to be made from 0.8mm Kraftplex. This comes as a puzzle card (108 x 65 mm) where all pieces are attached at one or two points. Strong fingernails and a pair of pointy pliers are recommended tools for assembly. Dimensions are 60 x 28 x 20 mm. Scale to 105% for an easier fit. 2019-03-31 update: fixed the pop-out connectors for the small one. Added a box for the small one. 2019-11-09 update: added FreeCAD drawing. <h3> How I Designed This</h3> The box was done with <a href="https://festi.info/boxes.py/UniversalBox?FingerJoint_angle=90&FingerJoint_surroundingspaces=2.0&FingerJoint_edge_width=1.0&FingerJoint_finger=0.3333&FingerJoint_play=0.0&FingerJoint_space=0.3333&FingerJoint_width=0.3333&Stackable_angle=60&Stackable_height=2.0&Stackable_holedistance=1.0&Stackable_width=4.0&Hinge_grip_percentage=0&Hinge_outset=0&Hinge_pinwidth=0.5&Hinge_style=outset&Hinge_axle=2&Hinge_grip_length=0&Hinge_hingestrength=1&CabinetHinge_bore=3.2&CabinetHinge_eyes_per_hinge=5&CabinetHinge_hinges=2&CabinetHinge_style=inside&CabinetHinge_eye=1.5&CabinetHinge_play=0.05&CabinetHinge_spacing=2.0&Lid_angle=90.0&Lid_second_pin=0&Lid_second_pin=1&Lid_spring=both&Lid_surroundingspaces=2.0&Lid_edge_width=1.0&Lid_finger=0&Lid_play=0.05&Lid_space=2.0&Lid_width=1.0&Click_angle=5&Click_bottom_radius=0.1&Click_depth=3.0&RoundedTriangleEdge_height=150.0&RoundedTriangleEdge_r_hole=2.0&RoundedTriangleEdge_radius=30.0&RoundedTriangleEdge_outset=1&Flex_stretch=1.05&Flex_connection=1.0&Flex_distance=0.5&Flex_width=5.0&top_edge=L&bottom_edge=F&x=60&y=25&h=30&lid=flat&thickness=3.0&format=svg&tabs=0.0&debug=0&reference=100&burn=0.05">https://festi.info/boxes.py/UniversalBox?FingerJoint\_angle=90&FingerJoint\_surroundingspaces=2.0&FingerJoint\_edge\_width=1.0&FingerJoint\_finger=0.3333&FingerJoint\_play=0.0&FingerJoint\_space=0.3333&FingerJoint\_width=0.3333&Stackable\_angle=60&Stackable\_height=2.0&Stackable\_holedistance=1.0&Stackable\_width=4.0&Hinge\_grip\_percentage=0&Hinge\_outset=0&Hinge\_pinwidth=0.5&Hinge\_style=outset&Hinge\_axle=2&Hinge\_grip\_length=0&Hinge\_hingestrength=1&CabinetHinge\_bore=3.2&CabinetHinge\_eyes\_per\_hinge=5&CabinetHinge\_hinges=2&CabinetHinge\_style=inside&CabinetHinge\_eye=1.5&CabinetHinge\_play=0.05&CabinetHinge\_spacing=2.0&Lid\_angle=90.0&Lid\_second\_pin=0&Lid\_second\_pin=1&Lid\_spring=both&Lid\_surroundingspaces=2.0&Lid\_edge\_width=1.0&Lid\_finger=0&Lid\_play=0.05&Lid\_space=2.0&Lid\_width=1.0&Click\_angle=5&Click\_bottom\_radius=0.1&Click\_depth=3.0&RoundedTriangleEdge\_height=150.0&RoundedTriangleEdge\_r\_hole=2.0&RoundedTriangleEdge\_radius=30.0&RoundedTriangleEdge\_outset=1&Flex\_stretch=1.05&Flex\_connection=1.0&Flex\_distance=0.5&Flex\_width=5.0&top\_edge=L&bottom\_edge=F&x=60&y=25&h=30&lid=flat&thickness=3.0&format=svg&tabs=0.0&debug=0&reference=100&burn=0.05</a> Added some radii and made the springs in the lid 1mm stronger. The box came out as a tight pressfit despite the quite small burn value. The slot for the lid was widened by 0.1mm as 3mm Kraftplex is actually 3.1mm thick. Category: Vehicles
