Customizable Flanged Hole Reducer Adapter Insert
Print Profile(1)
Description
Turn any oversized hole into a neat, smaller pass-through with this parametric flanged reducer insert.
It’s built in three functional zones:
- Front flange: covers rough edges and gives a clean finished look
- Press-in insert: centers the part and guides it into the existing hole
- Retaining lip: adds a little “grab” to help the adapter stay seated once installed
Fully customizable fit
Every key dimension is adjustable in the Customizer / OpenSCAD parameters, so you can tune the fit for your exact project—panels, enclosures, printed parts, ducting, or any general pass-through for cables, tubing, screws, or hardware. Dial in the outer/inner diameters, heights, flange size, and lip geometry to match your material thickness and the amount of retention you want.
Common uses
- Panel/enclosure hole reduction
- Cable or tube pass-through / grommet-style insert
- Bushing-like sleeve for hardware
- Clean edge finishing for cutouts (3D printed or CNC)
- Quick adapters for mismatched openings
Printing tips
- Print flange-side down for the best surface finish and strength.
- For a press-fit, start with small tolerances and adjust based on your printer/material (PLA/PETG/ABS) and real hole accuracy—measure, tweak, reprint, done.
