Кювета - Параметрический держатель Eppendorf

Fully parametric Cuvette/Eppendorf holder

Cuvette Holder Stand - Eppendorf tube fully modular.

In a biology laboratory it is often necessary to work with instruments such as spectrophotometers and spectrofluorimeters. In general there are many types of cuvettes and/or containers that need to be stored.

Based on the experience gained from working in a theoretical and computational biochemistry laboratory, comparing myself with colleagues who are behind a counter every day, I decided to propose this simple, but very interesting design.

The project in particular consists of two fully modular 3d designs for producing stands for laboratory Cuvettes and different kinds of Eppendorf (the classic microprovettes).

Both files are editable via Autodesk Fusion. It will be possible to edit dimensions and numbers (rows and columns) of the cuvette/Eppendorf stands, hole depth and total height of the stand.Below is a table with the names of the project parameters:

Parameters in common are not explained twice.

The designs are meant to be printed quickly and without excessive quality (they should be functional, not beautiful). The type of material used will not be a problem for normal lab activities, it will be possible to keep the stand at room temperature and in cryogenic refrigerators (if you use PLA DO NOT AUTOCLAVE).

The prototypes I have created have been printed in PLA and have not been damaged in any way.

The design is meant to be lightweight (minimum 5% infill) and for this very reason I recommend increasing the number of top layers to ensure a uniform finish without unevenness.

Printing parameters:

Layer Height:0.2 (but 0.3 is fine if time is the main issue, I would do some tolerance testing though)Top Layer:10Infill:5% (Grid)
