beekeeping entrance disc

This is a clean, fully functional 50mm Beehive Entrance Disc (Fluglochscheibe) designed specifically for nucleus boxes and queen mating hives. It features 4 quick-select positions so you can manage your colony in seconds just by spinning the dial:

• 🟢 Fully Open (15mm): Unrestricted traffic for the busy nectar flow.
• 🟡 Queen Excluder (4mm slots): Lets your worker bees come and go freely, but keeps the queen safely locked inside the box.
• 🔵 Ventilation Grid (2mm gaps): Perfect for transporting the nuc or keeping the bees safely inside during pesticide spraying without suffocating them.
• 🔴 Fully Closed: Solid shut-off for wintering or moving the hive.

📐 Technical Specs:

• Outer Diameter: 50 mm
• Main Openings: 15 mm
• Queen Excluder Slots: exactly 4.0 mm
• Ventilation Grid: 2.0 mm gaps / 1.5 mm ribs
• Mounting: Standard center pivot hole (just use a small wood screw, don't overtighten so it can still spin!).

🖨️ Print Settings & Tips:

• Material: PETG or ASA strongly recommended. (Do not use PLA – it might warp and jam in the hot summer sun)

Happy beekeeping! 🐝
