Snap-together, stackable bridge / riser for wooden train sets (Brio, IKEA, etc).

No extra hardware needed, requires minimal supports (only for snaps), and prints track-side up. A complete unit has 1 track and 2 sides. Can be stacked at 0 or 90 degree angle for multilevel parallel tracks or crossovers.

V1.2 is nearly identical to V1.1 but simpler geometry. Changes in V1.2:

• Greatly reduced triangle count

• Re-cut snap fit holes to fix geometry issues

• Slightly less distance between left and right snap-fit holes

• Slightly less space between arches

Changes in V1.1:

• Dropped height slightly on legs for better height-compatibility with other elevated track pieces

• Bigger snap-fit clips and hole

• Added ramped edges in snap-fit hole for easier snapping together

• Added ramped edges around edge of track piece for easier stacking

Printing and Assembling

Print two sets of legs and one track piece.

Print track and legs for V1 OR V1.1+, don't mix and match with V1 because V1 snap-fits are not compatible with other versions. I've had success with adaptive/variable layer height, supports for the legs (snap-fit part), and no supports for the track.

When assembling, the two pairs of legs snap into the bottom of the track. Make sure the arch platform faces inward to support other track attached to the riser.
