I printed with PLA and PETG. Might be best printed with PETG on a textured sheet. You will get the texture as a surface.
Was inspired by this design from Jezric on thingiverse that did not match my track height.
His Fences will fit my outer borders.
The design was done in onShape and can be found here.
The author marked this model as their own original creation.
