GPGF - Gridfinity ER32 Collet Holders

Why I made this:

• I finally put a ER32 collet chuck on my little lathe

• I got a bunch of collets for it:

  • These metric ones (1 mm - 20 mm)

  • These imperial ones (1/8 in - 3/4 in)

• I wanted to organize these collets in a drawer

Why this is cool:

• Organization is always cool!

• The collet holder blocks have crush ribs so you can press magnets in securely. I still use a drop of glue but you may not need it!

• The labels are separate from the blocks so that you can print the blocks with a big nozzle but print the detailed text on the labels with a fine nozzle.

Printing notes:

• Organizer blocks:

  • I recommend printing the organizer blocks with a 0.4 nozzle so that the crush ribs print nicely.

  • Maybe it would work with a 0.6 nozzle, but I didn't test this.

• Labels:

  • The labels have to be printed with a 0.2 nozzle.

  • Print the labels text-down on the build plate.

  • I printed the labels on a smooth plate for maximum legibility.

  • The 3MFs should be sliced ease of dual-material assignment.

  • Since the text isn't raised, the labels would of course print more efficiently with a dual-nozzle machine - but if you're printing a lot all at once, you can be efficient with your material swaps on a single-nozzle machine if that's what you're rocking.

Putting it together:

• You will need (4) 6 mm x 2 mm magnets per organizer block

• You will need as many magnets as you want for your baseplates

• Press magnets into the organizer bases before you install labels so that you can put the organizer block face down without resting it at an angle. Make sure you stick to a consistent magnet polarity!

• Put a dab of glue between the locating holes where the label goes, press the label into place.

• Et voilà!

Additional notes:

• I made the base bin geometry with this Onshape Featurescript for generating Gridfinity Bins.
