Valve with slider

I needed a valve for 160mm foam tubes used for a thermodynamic boiler.

I wanted my air intake to be taken from indoors (in hot spots just under the roof- during summer and outdoors (because I do not want to pump heat inside during cold days) during winter.

I therefore remixed the Valve made by MrFuzzy_F to:
- Have the valve printed easily in 3 parts (actually in 4 parts) because of the huge pipe diameter and the normal printer. The pieces are screwed together.
- Have one slider for the open position (green) and one for the closed position (red), again because I cannot print one slider that does both open and closed position due to the size.

This is working perfectly and since I change this twice a year, swapping the sliders is fine (and give me a color code, easily to see even from far away).

I only added a bunch of hours to suit my needs ;-)
