Parametric Gridfinity Bins w/ Quick Swap Labels - Swapfinity

Announcements

Version 1.0.0 is out now! 🎉 It is the result of testing and continuously improving the design over the last few months. No breaking changes, labels stay the same.

New features/improvements:

• New: Lots of new variants with and without compartments

• New: 1x1 bins automatically use the available space in the bottom of the bin (see comparison images). 4.75mm more space for parts for the same bin size. Can be turned on/off with a parameter. 

•  Improvement: improved stacking lip: bins fit better into the stacking lip on top and cannot hit the label shelf any more. Larger bins have bigger ‘stoppers’ so bins do not slide as easily over the border.

• Improvement: Labels are easier to remove through better spacing to the stacking lip

• Improvement: Improved inner bin geometry leads to much smoother surfaces and print movement.

• Improvement: Better support for smaller bins z < 3.

This model is part of the gridfinity compatible swapfinity series. You can check out all compatible models in this collection.🔗

Swapfinity 

Gridfinity compatible bins with quick swappable labels. 🚀 

I really like the concept of gridfinity, but the default label holders were too big and too inflexible for me. I wanted a non-intrusive label holder, so i created Swapfinity. I prefer not to remix STLs, so I recreated the gridfinity bins in Fusion 360 as a parametric model. 

Create bins of different sizes easily and use awesome 3d-printed labels in your gridfinity system.

If you need a specific bin or label with different sizes, text etc. let me know!

I am also open to improvements or suggestions.

Features:

• Quick swap labels with a non-blocking holder

• Print labels with text, icons etc.,  use blank versions and write on it with a pen or even use a label printer

• Parametric Fusion 360 model - change it to fit your needs

• Optional dividers that divide the x width of the bin into equal parts can be confgured

Usage:

Print the bins and labels. A label can be installed by slightly flexing it and putting the tabs into the pockets in the bin. The label can be uninstalled by putting a finger under it and pulling it upwards.

⚠Be careful and do not flex the label to much.

Printing:

⚠ The models were designed to be printed with a layer height of 0.2mm. I highly recommend to use 0.2mm as layer height. 

⚠ Slicers tend to hide the layer seems inside the label holder holes. Make sure to forbid seems inside the holes or use scarf seems to make the label fit well.

Bins: 

The bins are easy to print and do not need any supports.

I prefer to use PETG for them, but PLA works as well.

Labels:

If you just print blanks, you can use PETG or PLA.

If you print labels with text & icons, i recommend using PLA.

The text came out better with PLA in my tests.

Print them really slow to get the best results.

Even with a single nozzle printer without material change you can print labels by pausing the print at the correct layer and changing the filament .

Remixing:

The fusion files are available to download, so you can remix the bins to your needs.
Please share your remixes for others to use.

If you design your own labels, the height of the text, icons etc. should not exceed 0.6 mm. Otherwise the bins will stack at a slight angle.

Configuration Parameters

There are some configuration parameters available in the Fusion 360 files, that are meant to be changed if needed.

The most important ones are marked with a star.

• bin_scoop_size: Creates a scoop with the given radius to make fetching parts easier (disabled when equal to 0)

• x_u: width of the bin in u (one size unit)

• y_u: depth of the bin in u (one size unit)

• z_u: height of the bin in u (one height unit)

• compartments_x_amount: The amount of compartments. default: 1

• compartments_x_height_percent: The height of the compartment walls in percent in relation to the height available. default: 100

• deep_1x1u_bin: Whether to generate deep 1x1 bins. default: 1 (true)

⚠ Changing the label holder & label snap parameters makes bins and labels incompatible with each other. Use the same values for all bins/labels. The default values worked well for me, but different printers may lead to other results.

⚠Only change parameters with calculated in their name if you are familiar with their function!

Versioning:

I use semantic versioning to version the bin models. 

Each bin model has a version number with three numbers: MAJOR.MINOR.PATCH.

The version number will change depending on the compatibility between the previous and the current version of the bins.
 

Meanings:

MAJOR: Major changes in important areas of the model, most likely different major versions are incompatible with each other

MINOR: Greater changes to the model, but still compatible with different minor versions of the same major version

PATCH:  Small changes, fixes etc. Fully compatible to other patch versions of the same minor version

Version Log:

• 0.1.3: First public release

• 0.1.4: Added a lot of improvements for the label holder

  • reduced the size of the label holder significantly

  • easier printing and less material & printing time needed

  • labels are easier to remove now

  • easier access to parts in the bin

  • labels are still hold tight

  • fully backwards compatible - no reprints needed

• 1.0.0

  • New: Lots of new variants with and without compartments

  • New: 1x1 bins automatically use the available space in the bottom of the bin (see comparison images). 4.75mm more space for parts for the same bin size. Can be turned on/off with a parameter. 

  •  Improvement: improved stacking lip: bins fit better into the stacking lip on top and cannot hit the label shelf any more. Larger bins have bigger ‘stoppers’ so bins do not slide as easily over the border.

  • Improvement: Labels are easier to remove through better spacing to the stacking lip

  • Improvement: Improved inner bin geometry leads to much smoother surfaces and print movement.

  • Improvement: Better support for smaller bins z < 3.

  • fully backwards compatible - no reprints needed

• 22.01.25: added step files for the blank label

• 24.01.25: added pan head screw labels; added label table to display what labels are available

• 19.02.25: added compression spring label variants: add blank compression spring labels

• 22.03.25: added link to swapfinity collection

• 09.11.25: released version 1.0.0 with lots of improvements🎉

Future Plans:

• Filled bins for creating holders for tools, parts, equipment etc. (will be a different model)

• Need some new ideas :)

Known Todos/Issues:

• The fusion file needs some clean-up

• The hold of the labels becomes weaker with wider containers (can be fixed by changing parameters)

• Different labels are created by copying the main file and modelling them in the copy. I have not found a good/better workflow for that yet.
