modifying files

The computer files for Model  3 are provided as *.STL format in Shapeways.

​Remember you need to create an account on Shapeways to access these. Registration is free.

The files can be modified to change the design after importing them into suitable software programs.

Sites such as Shapeways have a lot of tutorials about 3D printing, see here

They also have a page with different free software you can download, look here

The program that appears the most popular is TinkerCAD www.tinkercad.com/, the other is SketchUp www.sketchup.com/download 

Examples of reasons for modifying include changing the slot dimensions, changing the shape of the airway insert, or to modify the insert so that a long silicone tube can be fitted (thus allowing the sampler to be located discretely in a bag). 

Other components that may require modifying include the top enclosure if a clock with a different-sized shaft is used. It may be necessary to slightly change the timer wheel, either for different thicknesses of sampling surface or to accommodate the hour hand of a different clock than we have used. 

You may want to use Model 1, 2 or 3 as a starting point and design your own sampler using some of their components

Confession: Modifying files is not a journey that I (Euan) have successfully undertaken; that is why I use a skilled designer who brings so many more skills and experience to the table, including insights into how designs 'work', as well as the production and materials use. Even for an experienced person lots can go wrong. People tell me it's not too difficult to do the basics, and I believe them.
