A compact (1u x 3u x 3u [X Y Z]), stackable Gridfinity bin for your Pinecil and Heat Set Insert tips. Heat insert tool holes have labels which can be printed in a contrasting color for higher visibility. The tip bin can hold up to four tips in the alternating arrangement demonstrated by Sweet1227's bin design (Note: tips must be < 110mm long). Due to the height of some of the insert tools, the Pinecil bin must be on the top and cannot have another bin stacked on top of it.

NOTE: While I think this would likely work for most of TS-100 compatible heat set insert tip sets, I used this one. The approximate outer dimensions of each of the tips are outlined below. If this matches what you have, the bin should work for you. Keep in mind that since the Pinecil bin is on top and can't be stacked, the diameter is the most important dimension to match for the tips. Because the adapter lays on its side, both diameter and length should be approximately the same.

M2: 7mm (D) X 12mm (L)

M2.5: 7mm (D) X 12mm (L)

M3: 7mm (D) X 16.5mm (L)

M4: 6.5m (D) X 17.5mm (L)

M5: 7mm (D) X 17.5mm (L)

M6: 7mm (D) X 12.5mm (L)

M8: 9mm (D) X 12.5mm (L)

Adapter: 6.5mm (D) X 34mm (L)

UPDATE (02/15/26): Updated to include a 4U deep main tray that allows stacking. The new tray accomodates heat set inserts with a maximum length of ~21 mm. Please note that using the 4U + 3U stack will result in the stack standing 1U proud of standard 6U Gridfinity height systems. Unfortunately, due to the diameter of tip collars, the tip tray could not be reduced to 2U to accomodate.
