3D Wolsung Terrain (spring cleaning challenge 2023)
Rounded corner walkway
I started this idea about a month ago, because all the little issue i ran into it was put on hold. i was working on a lot of 10 to 20 hours prints so i would print a part weeks apart.
This is the finished idea.
Basically i created a square box the size of the walkway then created an negative arc to remove most of that box. to get a shape i need to remove to get a nice curve. lastly i had to elongated the tabs to hold my rails. Off to the slicer and the printer.
Test print. 
I use para cord to measure the curve. I guess there is some formula to calculate this, but this method work for me
I measured about 105mm for curve
In Tinker CAD, i had to splice two rail images together and get 106mm length of rail that match and then i shrank it to 105mm.
First mistake made the creating the arch 105mm in length and it bends pass the edge of the corner walkway. I would shrink this to 90mm.
Something off, I forgot to create a mirror of arch, because time between prints. My slicer can do this easily . 
Finished corner are printed in pairs to make sure i have all the right parts assemble.
tight fit
