Plate with screwable cylindrical pins for repotting plants. Two parts to print: the plate (threaded holes) and the pins (male thread + flange).

Complete soil moisture measurement system using tensiometry. Includes the slotted probe tube for water flow, and electronic housings for the probe and receiver. All dimensions are fully parametric.
