Universal EURO 1/4″ Air-Tool Dock — Slide-On Crate Mount + M4 Screw Option | Up-Dock Gravity Capture | No-Support Print (Light & Solid)

Smart EURO 1/4″ air-tool dock that mounts two ways: slides onto toolbox/crate ribs or fastens with a single M4 screw. Up-dock action with an internal gravity shelf—perfect for blow guns, spray guns and hoses. No supports. Light & Solid variants for PLA/PETG/ASA/ABS/TPU.

Description

This compact, workshop-proof holder parks any pneumatic tool fitted with a EURO (European profile) 1/4″ male plug. Unlike generic hooks, this design uses an upward insert (“up-dock”): push the plug up into the downward-facing cavity until it seats on the internal shelf—gravity then keeps it captured. A keyed, anti-rotation channel stops wobble so tools sit quiet and tight.

Mount it two ways:

Slide-On Rib Mount — the integrated rear rail slides onto the rib of modular tool crates/toolboxes (as shown in the photos).

M4 Screw Mount — use the built-in hole to fix it to walls, vans, cabinets or pegboards with a 4 mm screw (+ washer).

Choose Light for everyday blow guns and short hoses; select Solid for heavier spray guns, longer hoses and high-vibration environments. Every model is tuned to print without supports and with clean chamfers at the mouth for smooth up-docking.

Ideal for: garages, body shops, service vans, compressor carts, assembly lines, and any tool wall or crate that needs fast, neat storage of air tools and quick-coupled hoses.

Light = leaner infill/walls for typical hand tools.

Solid = reinforced for heavy tools/hoses and mobile setups.

Compatibility

EURO/European profile 1/4″ male plug (the nipple threaded into your tool).

Works with blow guns, spray guns, nailers, sanders, quick-coupled hoses, etc.—as long as they have a EURO male plug installed.

Not designed for US Milton/Industrial/ARO profiles unless your tool uses a EURO plug.

Printing (no supports)

Orientation: Back face on the bed, cavity/mouth facing up.

Nozzle: 0.4 mm (0.6 mm great for Solid).

Layer height: 0.20 mm (0.20–0.28 mm for Solid).

Perimeters: Light 3+ | Solid 4–5

Top/Bottom: Light 4 | Solid 6–8

Infill: Light 15–25 % (gyroid/rectilinear) | Solid 35–60 %

Material & temps (typical; tune as needed):

PLA / Hyper-PLA: 200–215 °C nozzle, 55–60 °C bed

PETG: 235–250 °C nozzle, 75–85 °C bed

ABS: 240–255 °C nozzle, 90–105 °C bed (enclosure)

ASA: 245–260 °C nozzle, 90–105 °C bed (enclosure, UV-tough)

TPU (95–98A): 215–230 °C nozzle, 40–60 °C bed, 20–30 mm/s

For spray guns/long hoses, use PETG-SOLID, ASA-SOLID, or ABS-SOLID (4–5 walls, ~50 % infill). TPU-SOLID adds soft, rattle-free parking.

Mounting

Slide-On Crate Mount: align the rear rail with a crate/toolbox rib and slide on from the side until fully seated.

M4 Screw Mount: pilot the surface and fix with an M4 (4 mm) screw + washer.

Optional VHB/foam tape can supplement, but use screws for heavy tools.

Use

1. Hold your tool by the handle.

2. Push the EURO plug up into the holder’s cavity until you feel it seat on the internal shelf.

3. To remove, lift up ~5–8 mm to clear the shelf, then pull down/out.

Fit tuning

If the plug feels tight, scale X/Y +0.5–1.0 % or set horizontal expansion +0.10 mm.

If loose, scale X/Y −0.5 % or set horizontal expansion −0.10 mm.

Lightly deburr the mouth if needed.

Safety & load

Use the Solid variant + secure mounting for heavy tools or mobile rigs.

Periodically inspect the holder in high-vibration environments.

Not for overhead lifting or as a step.
