My nephew loves trains, so I got him a little wooden train set from Ikea. Of course, his imagination is much larger than the tracks included. A quick google search turned up this dxf on thingiverse. A little Estlcam later, and I’ve got a test track:
I was just looking at that thing and thinking about trying to cut it. They are only cutting one side right? The store bought ones I saw were cut on both sides but I can’t imagine getting that to work.
It is only cut on one side, that is correct. The store-bought piece on the left has an integrated joiner thingy, but the one I cut on the right does not, so it’s easy to just turn it around if I need it to curve the other way. The Thingiverse poster suggests bolts and locknuts to make joiner thingies, but also includes a diagram of them if you want to cut some yourself.
