I designed this adapter for my son's train tracks.
- Use as little material as possible while still being strong.
- To flex inward slightly for tacks with tighter tolerances.
- Has chamfered edges to help them slide into place easier.
- Dimensions are based on common 0.4mm printer nozzles to facilitate slicing and printing.
I designed it in Fusion 360 by taking measurements from physical wooden train tracks.
Print from PLA, 0.2mm layers, 60mm/s. I used Hatchbox PLA.
