I was annoyed that I had lots of small boxes for my attachments for my rotary tool. So I was looking for a box that would hold all my Dremel tools compactly and neatly. However, I couldn't find one that met my needs, so I designed my own.

It is based on the “Parametric Box V2” model, but I designed the entire interior of the box according to my own ideas. 
It can be printed entirely without AMS. I uploaded two versions of the case lid, one with the Dremel logo cutouts and a clean lid without cutouts. 

There are also two versions of the inner lid, a transparent version and one for any color filament. The transparent version is solid, so you can't see any infill structure. The colored version has an infill of 10%. 
I like the frosted glass look created by the textured print plate, but if you use a smooth print plate or a PLA raft under the transparent PETG print, you can also achieve a very transparent finish with the right filament settings. 
Since I generally like the textured surface left by the textured PEI plate, I created insert panels that can be glued into the box to create a (multi-colored) textured surface inside the box.
In addition, the 3 x 3 holes at the bottom left are 27 mm deep, while the rest are 32 mm deep. This allows shorter bits to be used there comfortably.

The hinges and clasps are connected to the box using 1.75 mm filament. 
I used round magnets with a diameter of 3mm and a height of 2mm to secure the inner lid. The magnet in the inner lid is inserted during printing, so I added a pause before the 23rd layer. There you can insert the magnet and continue printing. I would recommend inserting the magnet into the box only after the magnet in the inner lid has been installed. This allows you to check the installation direction of the magnet for the box and prevent incorrect installation of the magnet. This would keep the lid permanently open instead of closing it. 

To install the inner lid, simply insert the lid into the slot in the wall of the box and secure it with the locking piece. In my case, it was a press fit, so I didn't need any adhesive to glue the locking piece into the box. This has the advantage that I can remove and replace the lid if necessary.

In my prototype shown in the pictures, the spacing of the socket wrench cutouts at the top right was not quite correct, which is why the wrenches were too close to the wall of the box in the picture. I have corrected this in the current models.
