HC-SR04 Box

Made this mountingbox for myself to mesure the amount of wooden pellets that i have left for my furnace. But figured that someone else might find use for it. its modeld in Fusion360, and has a snapin lid were the sensor i mounted. also made provisions for a cablegland.The box is not watertight and should therefore be used indoors, or under a roof. i printed it useing Addnorth PLA, but i guess u could use any other filament u have in hand.the HC-sr04 has 4 mounting holes in the board for screws, but i havent modeld those holes in to the lid since they are very small. I guess u could just screw them in to the plastic.
