A customizable pneumatic mounting bracket for filters, water separators, regulators, lubricators, oil mist units and other cylindrical air-line components. The design is editable in OpenSCAD, making it easy to change the hole diameter, overall size, thickness and mounting-hole layout for different workshop setups.

Long Product Description

This is a universal pneumatic holder bracket designed for workshop air-line components such as water separators, pneumatic filters, pressure regulators, lubricators, oil mist units and similar cylindrical housings.

Instead of being locked to one brand or one exact part number, the model is built as an editable OpenSCAD design. That makes it easy to adapt for different diameters, different plate sizes and different screw-hole layouts without rebuilding the bracket from scratch. Se bottom of the side for instructions how to edit/measure.

The design philosophy is simple:

- stable mounting base

- vertical support plate with a circular opening

- optional reinforcement depending on the weight of the component

- straightforward geometry that is easy to print and easy to modify

This makes the model useful as a reusable base design for many kinds of compressed-air accessories. It is suitable for workshop walls, machine frames, tool stations, air-line panels and similar mounting surfaces.

Best Use Cases

- Water separators

- Pneumatic filters

- Regulators

- Lubricators / oil mist units

- FRL components

- Small cylindrical air-treatment modules

- Custom workshop air-line accessories

Key Features

- Universal pneumatic bracket concept

- Editable OpenSCAD source

- Easy diameter adjustment

- Easy base-size adjustment

- Easy mounting-hole customization

- Suitable for light, medium or heavier parts depending on thickness settings

- Good for workshop organization and wall mounting

- Practical one-piece print design

Why This Design Is Useful

Most pneumatic accessories are similar in principle but vary in diameter, body height and mounting requirements. By using a parametric SCAD file, the same base design can be reused for many products. You only need to adjust a few variables at the top of the file and re-export a new STL.

How to Customize the SCAD File

Open the SCAD file in OpenSCAD and edit the main variables near the top of the design.

Most important variables

- `hole_d` = opening diameter

- `base_w` = base width

- `base_d` = base depth

- `base_t` = base thickness

- `upright_w` = width of the vertical plate

- `upright_t` = thickness of the vertical plate

- `upright_h` = total height of the vertical plate

- `hole_z` = vertical placement of the hole center

- `mount_d` = mounting-hole diameter

- `hole_x` / `hole_y` or `hole_spacing_x` / `hole_spacing_y` = screw-hole placement

- `gusset_h`, `gusset_len`, `web_t` or similar = reinforcement dimensions when applicable

How to measure correctly

1. Measure the largest outside diameter of the part.

2. Always use the largest measured value.

3. Add print clearance.

4. Move the opening vertically with `hole_z` until the part sits at the right height.

Recommended fit allowance for PETG

- Tight fit: +0.6 to +0.8 mm

- Balanced fit: +0.8 to +1.2 mm

- Easy fit / imperfectly round part: +1.2 to +1.8 mm

Example

If your component measures 58.2 mm at the largest point, a good first value is:

- `hole_d = 59.8;`

## OpenSCAD Editing Workflow

1. Open the SCAD file in OpenSCAD.

2. Find the parameter block at the top of the file.

3. Change the values you need.

4. Press Preview.

5. Check size, fit and hole placement.

6. Press Render.

7. Export as STL.
