Dovetail Fit Test Pair

Create exclusively a small test model to check the fit of the dovetail sliding system for my modular organizer. Do not create any organizer modules or a complete base. The test model consists of a small rectangular base plate measuring 90 × 60 × 10 mm. On top of the plate, create two parallel dovetail rails running along the entire 60 mm length. Their centerlines are each positioned 15 mm from the long outer edges, resulting in a center-to-center spacing of exactly 30 mm. Each rail is 3 mm high, 8 mm wide at the base, and 10 mm wide at the top. Additionally, create a compact rectangular test block measuring 80 × 40 × 8 mm. Its underside features two matching, continuous dovetail grooves. The distance between the groove centerlines must be exactly 30 mm. The groove openings are 10.5 mm wide and taper inward to 8.5 mm over a depth of 3.25 mm. Allow approximately 0.25 mm of lateral clearance per side and about 0.25 mm of additional vertical clearance. The grooves must be open at both ends so that the test block can slide lengthwise onto both rails. Ensure that the undercuts are geometrically correct and suitable for FDM printing. Create both parts as separate bodies within the same CAD project. Show them both separately and in the assembled sliding position. Minimize PLA consumption and ensure the parts can be printed without unnecessary support structures. Do not include organizer containers, additional components, magnets, logos, or decorations. The sole purpose is to test whether the sliding dovetail connection fits smoothly while minimizing unwanted play.
