日常耳環(huán)#73：微型滑動火車環(huán)4cm

This is still under cotructio, expect the color photos, aditional carts and major tweaking in the future.
The wheels do not turn, it's just a slide rail- but works fine!
We decided to make it without loop and hook the rail to a big closure ring.
UPDATE 1: Added a color veion with a tunnel and pine, which also has a modified rail. Not tested! No STL yet.
UPDATE 2: Added a new SKP file. The new rail prints with texture, at least the main rails; I added 0.1mm height to the wood ba, should print now (hopefully).
The tree/tunnel veion did print, but the tree was disattached. Should work now- but its very big with those extras. I might do a 3cm rail veion with smaller train, but not today.
Printing the rail upside-down makes it much smoother and the train ru nicely, so this is the best orientation.
The train itself prints best facing up, as the glider clamp is more rigid due to the layer orientation then.
I made them 0,1mm shorter as on the original now, else they are hard to get on (and it still should be tight enough).
Added some images as well.
