Shelf Support Drilling Jig (System 32)

Drilling jig for Italiana Ferramenta shelf supports in System 32 cabinets. Covers the Flipper/Unico (Ø15mm, 6.5mm setback), PK2/PK2 Pro (Ø18mm, 8mm setback), and Kintai (Ø8×22mm counterbore + Ø15.5mm through-hole, 6mm setback), all on the standard 37mm System 32 pitch.

The jig clamps directly to the panel edge via an integrated cam lever (M8 thread), accommodating panel thicknesses from 6 to 30mm. It indexes off both the panel edge and the 37mm System 32 hole spacing for consistent placement. It can also be printed without the clamp for use with a separate hold-down method. The top plate is a separate component and carries the labelled hole positions (A/B) for both bushing sizes. Assembly uses M4x6mm threaded inserts throughout.

The jig body has a modelled M22×1.5 threaded socket for interchangeable drill guide bushings, so a single body covers all supported hardware types. Bushing models are included for both Ø15mm and Ø18mm. PA6-GF is adequate for printed bushings, but metal is preferable for longevity. M22×1.5 drill guide bushings are a standard size and can be sourced locally or via sites such as AliExpress.

STEP files included for all components.
