babo-hex-box

Hex driver (Allen wrench, hex wrench, Allen key, hex key, Inbus…) storage designed to fit in a Babo Organizer 30mm drawer https://www.printables.com/model/576213-babo-drawer-modul-30/comments. although quite useful independently.

I, like many if not most printer owners, have more than my share of Hex drivers and most are not used very often. The four sizes: 1.5mm, 2mm, 2.5mm, & 3mm are exceptions. They get used quite frequently either working on one of my printers or fastening together the pieces of a model. I have a set made of of one each of these sizes which are used at least daily. My set or at least ones nigh indistinguishable from it are sold under numerous brand names. They are inexpensive and hold up well.

This box, organizer if you prefer stores them in a space-efficient side by side arrangement.

Printing

• Supports: none
• Material: PLA or PETG or whatever. I printed mine with PETG
• Layer: 0.20
• Infill:   10% or better, cubic is what I used, but grid or gyroid would be fine at 10%

Final $0.02

If you decide to print with PETG I'd recommend you NOT iron the top layer. It will [likely] not play well with the recessed text. If you look at the photograph I included you can easily see the bit of clean up I did because of deciding to enable ironing for this model with PETG - oops.
Should be less of a concern with PLA, although I have not tested it. 

Babo Organizer

Babo Organizer is exceptionally well-designed drawer-based organizer by Willi (https://www.printables.com/@Willi) which is focused on 3d Printing needs. It includes not only a range of drawer sizes, but numerous dedicated addons (such as this project) by both the designer and the community. Most of the models, including the critical ones are openly available with a handful of specialty ones available to “club” members or for a modest fee. 

Willi's is the one Printables club of which I am a member.
