Eklind metric ball-hex driver holder compact with built-in retention springs - now including OpenSCAD file.

The popular EKLIND 92600 PSD Ball-Hex (allen) Precision Screwdriver set comes in an annoying plastic bag.  This is a much more convenient way to store and transport them. Perfect for both in-drawer and in-toolbag.  Drivers won't slide out even if held vertically.

The drivers interleave from both sides to make a very compact “block”.  The fit does not need to be overly precise – instead, internal PLA print-in-place springs (orange near the bottom of the cross section of one column on right) 

press in on the sides of the hex shaft and keep the drivers from falling out, but leave them easy to insert and extract.  The cylinder for each tool includes a funnel that guides the metal shaft into the smaller part, as shown.  The handles themselves fit in snugly part-way, as shown in the photos.

As shown in the 3MF file, these print vertically without supports or brim.  I used 0.4mm nozzles and the 0.20mm STRUCTURAL preset for my XL, only changing the infill from grid to rectilinear.  I used PLA but probably anything would do.

The 3MF file is a two-color print so that each storage position is not only sized to the corresponding driver but also labeled on both sides of the block.
