I made aluminum counterpart of V Slot Rail to print with ABS / PLA
Main features of this design are
- Reinforced at Corners (inside)
- Made thick channels
- Smooth exterior corners
It's made as small part in STL (L 20mm x W 20 mm x H 10mm)
Just increase height of the file on your slicer/printing program for desired length.
Note# Try to print along z Axis with some BRIM without any support material.
