Modular Storage System for 125 mm Grinding Discs & Workshop Accessories

# Modular Storage System for 125 mm Grinding Discs & Workshop Accessories

I designed and 3D printed this modular storage system for grinding discs, cutting discs and workshop accessories to bring more organization to my workshop.

The main idea was to create a system that is flexible, expandable and easy to customize. All modules can be combined and stacked as needed, allowing you to build your own storage solution depending on the available space and the items you want to store.

Thanks to the open design of the disc modules, you can immediately see which grinding discs are available and how many are left. This makes it easy to notice when a certain type is running low, so you can order replacements before you run out.

## Modular Design

The system now consists of six different module types, which can be freely combined with each other:

• Low compartment – ideal for smaller quantities or thinner grinding and cutting discs

• High compartment – provides more space for larger quantities and thicker grinding accessories

• Vertical disc holder – allows discs to be stored upright, one behind another

• Small drawer module – a compact drawer for smaller workshop accessories, spare parts or consumables

• Large drawer module – offers significantly more storage space for larger accessories, tools or additional workshop supplies

• Top cover / finishing module – provides a clean upper finish for the storage system

## Two New Drawer Options

I have added two different drawer modules to make the system even more versatile.

The small drawer is ideal for smaller items that would otherwise easily get lost in the workshop, while the large drawer provides considerably more storage space.

Both drawer modules are fully compatible with the other parts of the system. They can be stacked, combined and positioned as desired, so you can mix open disc storage and closed drawers within the same organizer.

This means the system is no longer limited to grinding discs – it can also be used as a practical general-purpose workshop organizer.

## Perfect for 125 mm Grinding Discs

The open storage modules are especially designed for the commonly used 125 mm discs found in many workshops.

They are ideal for organizing:

• Cutting discs

• Grinding discs

• Rough grinding discs

• Flap discs

• Fiber discs

• Sanding discs

• Other 125 mm grinding and sanding accessories

Different types of discs can be separated into individual compartments, making them easy to identify and access.

## See Your Stock at a Glance

One of the biggest advantages of the open compartments is the immediate overview of your supplies.

You can see at a glance:

• Which types of discs are available

• How many discs are left

• Which compartment needs to be refilled

• When it is time to order new supplies

No more searching through cardboard boxes, drawers or cabinets just to find out whether you still have the right disc available.

## Expandable and Flexible

The biggest advantage of this design is its modular construction.

You decide how your organizer should look.

Combine open compartments, vertical disc holders, small drawers, large drawers and the top cover to create a storage system that perfectly matches your workshop.

If you need more storage space later, simply print additional modules and expand the system.

This makes the organizer suitable for:

• Workshops

• Garages

• Hobby rooms

• Metalworking areas

• Grinding and welding stations

• Tool storage areas

• Workbenches

• General workshop organization

Print it, stack it, combine it and expand it – build your own modular workshop storage system!

# Recommended 3D Printing Settings

The modules can be printed in PLA or PETG.

PLA is perfectly suitable for normal indoor workshop use and is easy to print. PETG is a good alternative if you prefer a little more toughness and better temperature resistance.

## PLA

• Nozzle: 0.4 mm

• Layer height: 0.20–0.24 mm

• Walls / Perimeters: 3–4

• Top / Bottom layers: 4–5

• Infill: 15–20%

• Infill pattern: Gyroid or Grid

• Nozzle temperature: 200–220 °C

• Bed temperature: 50–60 °C

• Cooling: 100% after the first layers

• Print speed: approx. 60–120 mm/s

• Supports: Normally not required

## PETG

• Nozzle: 0.4 mm

• Layer height: 0.20–0.24 mm

• Walls / Perimeters: 3–4

• Top / Bottom layers: 4–5

• Infill: 15–20%

• Infill pattern: Gyroid or Grid

• Nozzle temperature: 230–250 °C

• Bed temperature: 70–85 °C

• Cooling: approx. 30–60%

• Print speed: approx. 50–100 mm/s

• Supports: Normally not required

> Tip: I recommend using at least 3 walls/perimeters for all modules. For a more robust workshop setup, especially when stacking several modules or loading the drawers with heavier items, 4 walls/perimeters are recommended.
