Hello
With some little more work is possible to add a sliding canopyof good effect.
I have realized a small kit to cnc that allows to get a very soft movement and to regulate. To eliminate the possible attrition, has added some strips of polipropylene where they have put the screws, that it has a power self-lubricant. The photos are surely more explanatory.
