The Redstone Connected Sensor at the front can be placed ontop of the Crucible facing backwards and then adjusted with the monkey Wrench to Detect whatever is below it while it still faces backwards physically, giving you space for one more Mold, just be sure to not have Droppers/Dispensers adjacent to the Sensor itself, meaning you should just put it one further up, and then use something like Microblocks, unused Sensors, Trapdoors or alike to adjust the flight trajectory of the dropped items fro mthe back droppers properly.
