This model replicates the functionality of a traditional wooden Langstroth entrance reducer while optimizing for standard FDM build volumes. The geometry is split into two interlocking pieces that connect via a precision dovetail joint, allowing a full 14.75-inch (374.65 mm) 10-frame reducer to be printed flat on standard 8.6-inch (220 mm) to 10-inch (256 mm) build plates. The design includes a dual-notch system: a larger opening for summer ventilation and a restricted opening to defend against robbing behavior during seasonal dearths.
I would really like to see photos of your prints, and let me know if there are any changes or tweaks you would like to see.
Print Settings
Material: PETG (PLA may deform under normal hive temperatures).
Layer Height: 0.20 mm
Perimeters: 4
Infill: 30% Rectilinear
Orientation: Print both halves entirely flat on their longest solid faces positioned so there are no overhangs.
Supports: None.
Assembly Instructions
Summary of the steps: Clear print artifacts and assemble the dovetail joint.
Inspect the male and female dovetail geometries and remove any stringing or first-layer expansion (elephant's foot) to ensure proper mechanical clearance.
Slide the two halves together to lock the dovetail; optionally apply CA glue inside the joint prior to assembly if a permanent, rigid reducer is preferred.
