The goals for this design were to provide a space saving method to store component tapes of different sizes that also lets you directly use the components for assembly. I came up with a design which, at least for me, solves the problem.

It …

• ... is fully parametric
• ... is fully 3D printable (no additional parts required)
• ... supports labeling (flat surface)
• ... supports waterproof markers
• ... has an integrated spring mechanism to securely hold the tapes
• ... has a cover tape slot
• ... makes a satisfying click when correctly assembled

To modify the design to suit your needs, you will need to use OpenSCAD (https://www.openscad.org). If you're not familiar with it, don’t worry. The only thing you need to do is provide table-like data. You’ll need to describe the dimensions of the tape using seven values, along with an additional parameter to define the tolerance.

tape([ 12.0, 2.7, 0.5, 1.0, 3.0, 1.0, 3.0], 0.2),
tape([  8.0, 1.3, 0.3, 1.0, 3.5, 1.0, 3.5], 0.2),
tape([    w,   h,  ht, wsl, wsr, wtl, wtr], tolerance),
 

Each line represents one rail on the tray. All values are in mm. The diagram should make things a bit clearer:

In addition to the custom dimensions, I’ve also included some generic presets that should fit most 8mm, 12mm, and 16mm tapes. I’ve provided two examples in the SCAD file to help you get started. After editing the dimensions, you will need to compile the model (F6) and export the STL (F7).

For those who don’t want to modify the design, I’ve generated trays with 8x8mm, 8x12mm, and 8x16mm slots, each with a length of 150mm, using the generic presets. If you want to test if your tapes fit the presets, there is also a pre-generated tester model.

Hope you like it!

Printing

• Use a flat bed for printing
• .2mm layers
• .4 nozzle
• I had really good results with PLA+

Assembly

Just slide the two halfs together until you hear a click.

If you want add a label or write directly onto the surface.
