This is the customizable bridge for 1/18th and 1/24th scale crawlers, like the TRX4M and SCX24.

There are 3 bridge support sizes, 50mm,100mm, and 150mm. Each bridge support comes in 2 variants, flared base, and stackable. The stackable variant is meant to be stacked on top of other bridge sections, and the flared base can stand on its own, but is also stackable if you don't want to print both sets.

There are 3 kinds of bridge sections, a starter ramp, connecting ramp, and flat bridge section. Each of these has a flat or ribbed variant depending on the traction you want. There is also a connector piece that allows you to connect multiple bridge sections together if you want it to span a longer distance.

The bridges and supports are fairly sturdy and can hold the weight of your rig with the connectors.

Turn the bridge sections and connectors sideways in your slicer and you can print them without supports. the bridge supports print fine without supports standing vertical.

*Edit 10/31/23 - Thickened the cross braces on the 150mm towers as they would sometimes fail during printing. (Replaced the "LiftBrdg 150mm skeleton stack" and "LiftBrdg 150mm skeleton flaired" with "LiftBrdg 150mm skeleton stack thick" and "LiftBrdg 150mm skeleton flaired thick")

*Edit 5/19/24 - Uploaded the 100mm and 150mm connected towers as requested. Named "LiftBrdg 100-150connected Skel Flair.stl" it keeps the 100mm tall towers and 150mm tall towers connected, and theoretically should help with stability. Keep in mind though, I am uploading this STL without first printing or testing it. Let me know if it works.
