Summary

This bridge was completely designed using research. It is a testable bridge what uses an arch and cables for strength. Use 1.75mm filament for the cables and print on its side. Instructions in below sections. I ADVISE USING PLA DUE TO ABS LAYER ADHESION ISSUES!!!!!

One side is not perfectly level and so (depending on slicer) wont print with first layer no matter how it is oreanted. This didn't cause any problems for me though. I will fix this soon.</p></div>

Post-Printing

Step 1

            <div><p>remove from printer and slide 1.75mm filament through a hole in an arch. Slide through corresponding hole in road. Cut to size leaving a small amount of extra filament on both sides. Do this for all holes and after each one, secure in place by melting the extra to the bridge ( I used a soildering iron).</p></div>
