Coin-sorting plate with three graduated drop windows

Sort round coins or flat tokens using three diameter thresholds. The plate has a continuous rolling ledge and three progressively larger drop windows. Hold it above your own collection containers, leaning slightly backward and downhill along the track so individually fed coins rest against the plate while rolling on edge. Small pieces can tip through the first suitable window; larger ones continue. Set window heights slightly above each measured group diameter and below the next group. The design adds 0.3 mm to the selected height and 2 mm to window width. Default thresholds are 18, 24 and 32 mm. Equal-diameter coins with different values cannot be distinguished. Adjust tilt and clearance with a few clean samples first. There is no counter or rated sorting throughput. Adjustable dimensions: First diameter threshold: 12–19 mm; Second diameter threshold: 20–25 mm; Third diameter threshold: 26–35 mm. Printing starting point: PETG, 0.2 mm layers and at least four walls. Check print tolerances and surfaces before use. Have your own 3D printer? Configure the dimensions, buy and download the matching STL file, then prepare the 3D model in your slicer. No printer?
