Summary

I designed this section of Toy Train Track for MakerBot printing. It's compatible with the Thomas, Ikea and Brio brand wood toy train tracks.

For larger objects, getting raft and lower layers to stay stuck can be a challenge. Earlier simple copies had serious warpage issues, so I changed to a lattice structure. This gives the lower layers a chance to flex and cool independent upper geometry. There was still some separation of the raft from the build platform, but it was minor compared to previous iterations.

The main track portion of the fabject is 54mm long and 40mm wide. Total length is 72mm.

Note: The socket-side tends to be a bit tight with some track; you may need to widen the hole for a looser fit.

Instructions

  1. Download the STL file.

  2. Raft in skeinforge to taste.

  3. Print.

  4. Play

  5. Download SketchUp file.

  6. Make it your own.

This is brilliant. How on earth did you make the lattice in sketchup?

Draw a closed shape on the surface of an object and use the Push/Pull tool to punch the shaped-hole through. Make sure the opposite side edge is accessible so you can 'snap' the hole to the other surface.

For the zones near the sockets it's better to type in a depth than punch all the way through. The model gets messy in transition areas from internal volume to holes and back again.

SketchUp doesn't have the support for proper geometric boolean operations.

Hey andrew think you could do a "turn" piece? My son has lost only 1 of the turns and now the train de-rails :). Trade you some laser cutting stuff :)

Very nice design modification to avoid warping!

A few more parts like this, and every 3 year old boy is going to want a Makerbot.

That is a SMART design addition.
