I really love the Dinzl Assortment Boxes by Dinzl Ordnungstechnik and i also love Gridfinity for organizing small parts. When i looked a both, if figured that they are an almost perfect match for 8x5x6u Gridfinity bins.

They are made under different names for quite a while now but the design changed from those made 20+ years ago - especially the hinges and the joints at the corners are slighty different. You can get them used of ebay for cheap or buy them brand new online here:

Compatibility / Printing

The inserts are currently compatible with all boxes with 340 x 240 x 50 mm. Figure out wich Version/Model you have (see images below if you unsure)

if you have one of the following, print the “new” Version

• Sortimentskoffer S50
• Sortimentskoffer SN50
• Sortimentskoffer SE50
• Sortimentskasten DIMA 77/1

else the “legacy” insert is right for you, since it has a bit of tolerance and also cutouts at the corners, to overcome damaged corners

Everything prints with no supports. PLA with 2 walls and 10 to 15 % Infill is plenty strong.

Print 2 pieces as is - they have a rotational symmetry (do not mirror them)

“new”:

• overlapped corner is inset slightly
• sharp corner with relieve hole
• hinge mounted on the outside

“legacy”:

• corner directly overlaps
• corner is drawn inwards
• hinge is mounted on the inside

Assembly

Put the 2 pieces together outside the box (no glue needed) and gently slide them in - on the legacy version, the hinge is on the inside, so you need to slightly bend and wiggle it in

If your box does not come with a foam on the top, glue some 3 to 4 mm soft foam on top of the lid to prevent small parts falling out the bins when the box is turned upside down
