Cullenect Swappable Labels for Gridfinity and More

CULLENECT SWAPPABLE LABEL SYSTEM

I love the look of printed labels, but I hated re-printing my bins whenever I needed to move my parts to a larger bin. I also hated how difficult it was to find consistent themed icons for all of the different kinds of screws and their drivers.

• Print your labels once and transfer between bins when you need to increase / decrease storage capacity.
• Assorted Gridfinity bins with label sockets built in are included, or generate your own bins with label sockets using “Gridfinity Extended”
• Add the label socket to any 3D printed object, including other Gridfinity bins, using the included negative volume in your slicer.
• Use the Customizer / OpenSCAD to generate custom labels of any size, larger or smaller.
• Download the complete collection to combine any combination of fastener + driver + label text. 

Mix and match screw types and driver types:

I generated a huge variety of screw types and driver types and to use them simply add them to your slicer and combine them, making hundreds of combinations possible!

I've added several print profiles for you to use, but these are just for convenience and you are free to create whatever labels your hardware requires.

Available icons currently in the collection:

Screw types:

• Machine screw with round head
• Machine screw with socket head
• Machine screw with pan head
• Machine screw with countersunk head

• Tapping / wood screw with countersunk head
• Partially threaded machine screw with round head
• Partially threaded machine screw with socket head
• Partially threaded machine screw with pan head
• Partially threaded machine screw with countersunk head
• Flange head (combine with any fastener head above except countersunk)

Driver types:

• Hex
• Phillips
• Phillips + Slot
• Phillips + Square
• Slot
• Square
• Torx / Star
• Triangle
• Security bit nub (combine with any driver above)

Hardware types:

• Nuts
• Washers
• Locking washers
• Threaded inserts
• T-Nuts
• Square nuts
• Nylon lock nuts
• Magnets
• Crimp rings
• Crimp forks
• Crimp spades
• Crimp receptacles

Pre-generated size text:

• M2x[3-75]
• M2.5x[3-75]
• M3x[3-75]
• M4x[3-75]
• M5x[3-75]
• M6x[3-75]

Available pre-made bins in the collection:

In addition to generating your own Cullenect bins here, I have packaged pre-made bins with the collection.

Pre-made bins are available in heights from 3U to 10U:

• 1x1
• 1x2
• 1x3
• 2x1
• 2x2
• 2x3
• 3x1
• 3x2

Compatible with almost any bin using negative volumes

In the collection I include a vertical and horizontal negative volume STEP file which you can use in your slicer to carve out the required space for the labels to be placed.

Slicer settings:

If the default settings cause labels to be too tight or too loose I recommend the following settings in your slicer:

• Elephant Foot Compensation: Start with default (0.15) and increase/decrease if the snap fit is too tight/loose.
• Brim: Disabled
• Wall Generator: Arachne
• Prime Tower: Optional, but recommended
• Layer Height:
  • 0.2mm nozzle: 0.1mm layer heights
  • 0.4mm nozzle: 0.2mm layer heights

How to download the complete collection:

It's not very obvious how to download the .zip file containing all of the .step files needed to create your own labels, so here are some instructions.

Click “Download or Print” and then “Download STL”

Click the download icon next to “Complete Collection”

Future changes and additions underway

Request screw / driver / hardware icons in the comments! I'll do my best to add them to the collection and list you as the requestor.

• SMD / THT icons (resistors, capacitors, etc.)
• PCB / Arduino
• XT60 / XT90 connectors and other power connectors
• Wing Nut and Carriage Bolts - Requested by naked-roots on Reddit.
• Adjustable icon size - requested by @zymex
• Dowel pins
• Serrated washers
• O-rings
• Bearings
• Heat shrink
• Drill bits
• Nails
•  

Tools, bins, or labels made by the community:

• Cullenect on Github - Repository for Cullenect labels on OpenSCAD.
• GFLABEL by Nicholas Devenish - A python script to generate click labels as seen here, or “Pred" style labels, also includes other icons such as resistors and other electrical components which I haven't implemented yet.
• Gridfinity Extended by Chris Heazlewood (Also on MakerWorld) - An OpenSCAD model for many Gridfinity bins and tools. Recently integrated the click labels. You can also use the Makerworld Model Maker to generate these bins right in your browser by visiting this model page.
• Cyberbrick Gridfinity bins adapted to Cullenect labels by yours truly. To fit the bins created by Bambulab I needed to reduce the label size to a non-standard 30x5mm.
