Stone Bridge 3d model

To build a basic, one arch bridge, you will need to print: 2 of bridge_arch.wall.stl or bridge_arch.wall.magnetic.stl 2 of bridge_arch.wall.mirrored.stl or bridge_arch.wall.magnetic.mirrored.stl 2 of bridge_top.wall.stl or bridge_top.wall.magnetic.stl 2 of bridge_top.wall.mirrored.stl or bridge_top.wall.magnetic.mirrored.stl 2 of bridge_ramp.wall.short.stl or bridge_ramp.wall.short.magnetic.stl 2 of bridge_ramp.wall.short.mirrored.stl or bridge_ramp.wall.short.magnetic.mirrored.stl For each additional arch in the center, print: 2 of bridge_arch.wall.span.stl or bridge_arch.wall.span.magnetic.stl 2 of bridge_top.wall.span.stl or bridge_top.wall.span.magnetic.stl If using magnets, the magnets are 1/8" x 3/32" disk magnets. You'll need a fair number of them. (9 4) arches, (2 4) tops, (8 4) ramps = 76 for a basic bridge, and another (6 2) arches, (4 * 2) tops = 20 for each additional span. Luckily, those magnets are only $1.40 per 10. You can use openlock, or even use a combination of openlock and magnets. A 1/8" drill bit is handy for clearing out the hole if it's not well cleared (because of say overextrusion). I use both magnets and openlock for different reasons.
