Compartmented container for screws or other small pieces

I don't charge for my functional models. Please consider purchasing some of my paid models as a way to support both my work, and this great website: https://www.printables.com/@ninjamida/store

Yet another printable container for your small pieces of hardware. The outer structure and the individual compartments are printed seperately, allowing mixing-and-matching freely of different sized compartments.

Uploaded models use a base size of 25mm x 30mm for the compartments, but you can download and modify the FreeCAD file to use any other size you like - there is a VarSet with almost all measurements defined in it, and you can generally just tweak that then re-export the files.

These containers are stackable with others of the same size. They generally do not remain stackable across different sizes, or if any of the dimensions are significantly changed.

The compartments have a sloped front with a rounded transition. While steep, I find it's enough to easily get screws and other small pieces out of the compartments.

Photos show the 6x2 configuration with 1x1, 2x1 and 1x2 compartments.

If you would like me to upload STLs of other arrangements besides the included ones, let me know.

Non-printed Parts
- 2x M3x20 screw, not countersunk
- 6x 3mm x 1mm round magnets (optional, but recommended)
- 35mm x 19mm label (optional)
- Superglue (may or may not be necessary depending on your printer's tolerances)

Print Settings
- Use whatever rigid material you like (I used PLA)
- Benefits from (but doesn't require) variable layer heights
- Supports are not required for any part, though may be desirable on the top part of the label holder in the BaseWithSlot variants
- Brim may be required for the larger parts depending on your setup and material choice
- A 0.4mm or smaller nozzle is recommended

Parts to print
- Print 1x base in your desired size, either the regular version (which has a recess for attaching a label) or the slot version (which has a holder for inserting a regular paper label)
- Print 1x lid in the same size
- Print compartments as desired to fill those spaces

Assembly
- Double-check the stacking first - place the base on top of the lid and see if it stacks correctly
- Rest the lid in place on top of the base, as it would be positioned when the container is closed
- Insert an M3x20 screw into the hole of each hinge and tighten. If the screw thread is loose, apply a small amount of superglue just under the head of the screw (I recommend finishing the assembly and making sure everything else fits before applying this superglue)
- Open the lid, and insert a 3mm x 1mm round magnet into each of the magnet holes in the base (if they will not fit, use a closely-sized hex or torx screwdriver bit to slightly widen the hole)
- Place a second 3mm x 1mm magnet on top of each magnet inserted into the base
- Close the lid, pressing down on the magnets to click the additional magnets into place in the lid
- If any magnets are not remaining in place, apply a tiny amount of superglue to the exposed end of the affected magnet, then close the lid again; reopen it after 5 minutes or so and allow to dry before proceeding (you may glue multiple magnets at the same time)
- Install the compartments. If need be, apply a small amount of superglue to the bump(s) on the base where you will be placing a compartment first. However, you may find that once all of them are installed, friction holds them in place
- Attach a label in the recessed space on the front of the base

With regard to the need or lack thereof for superglue - it's going to depend on your exact print settings and filament, as it's a very close margin as to whether it's needed or not. I've even found that, using the exact same settings but with two different colors of the same brand of PLA, I've needed to use the superglue with one and not with the other.
