This Gridfinity bin is designed to fit a Heat Insert Tip kit from Hanglife.  The set can be found on Amazon here.  Most heat insert tips should also fit this bin.

Other bins I found had no indicator where what size tip went into which hole.  I went ahead and designed my own, and embedded the M-size of the threaded insert into the base of the hole itself.  This should be a pretty straightforward bin to use, since some of the smaller tips have the same diameter, but different depths.  So if something is in the right hole, everything will fit flush.

I included two height sizes, 2 and 4 Gridfinity Units.  The 2U-high option fits everything great, but can't have things stacked on top if the set is in the bin.  The 4U-high option is fully stackable, plus it fits my other bins below for the threaded inserts themselves.

These are part of a set of Gridfinity organizer bins for screws, heat inserts, and rugged containers.  Others in this set are:

• Gridfinity Bins (Unlabeled) for Assorted Fasteners
• Gridfinity Bins for Kadrick heat inserts
• Gridfinity Bins for Ktehloy heat inserts
• Gridfinity Bins for M2-M5 Fasteners
• Gridfinity Bins for 4U Rugged Storage Boxes
• Gridfinity Bins for 5U Rugged Storage Boxes
• Gridfinity Rugged Storage Boxes V2

I've included PETG and PLA profiles, and have single color or multi-color options for both.
