Compact dual-ring mount for 9 mm FPV buzzer

Tiny one-piece mount designed as two cylindrical housings joined laterally. The larger ring provides the main mounting point and the smaller ring forms the cavity intended by the source for a 9 mm active buzzer. The entire STL envelope measures approximately 10.91 × 15.25 × 5.50 mm; the preview visually expands the piece so that the thickness, the two openings, and the tangential joint can be appreciated, but it does not alter its proportions. The source attributes the model to KarimXP, publishes it as Creative Commons — Public Domain, and declares no remix parents. The exact public search returns a single record belonging to Meshopia. The only official STL was downloaded and kept without photos, G-code, PDF, video, or machine files. Its mesh contains 476 vertices and 956 triangles in a single closed body. It opens correctly, uses finite coordinates, maintains consistent orientation, is watertight and manifold, and has no degenerate faces. Technical renders show no text, logos, brand reliefs, or additional parts. The references Sun250 and OasisFly35 are kept solely as compatibility declared by the source author; Meshopia has not verified the fit with a real chassis or a commercial relationship with its manufacturers. For a first FDM test, maintain 100% scale and use a fine layer height, around 0.12–0.20 mm, because a small variation greatly affects a 9 mm housing. A 0.4 mm nozzle can work if the slicer correctly maintains the walls; check the number of perimeters and the preview before printing. The most stable orientation usually supports the annular base on the bed with both axes vertical, avoiding supports inside the cavities, but confirm the actual bottom face in the slicer. The source describes a press-fit and a support-free print; both claims depend on material, shrinkage, flow, and tolerances. TPU may facilitate retention and vibration absorption if the model and printer support it; PETG can offer toughness, while PLA serves for a dimensional test, without any of them guaranteeing the result. Print one unit first, measure the actual diameter of the buzzer and the mount, and check that there is no excessive tension on the casing, cables, or solder joints. Deburr the interior without irregularly enlarging the rings. Before flying, verify that the part does not interfere with propellers, battery, antennas, electronics, or ventilation, and perform retention and vibration tests on the ground. There are no impact, fatigue, temperature, UV radiation, electromagnetic compatibility, or in-flight use tests. It is not a structural component, certified protector, or guarantee against buzzer loss.
