A list of our open source designs

:wave: We put all our available 3D printing files and designs on Printables.

We recently add a blank vial cap you can use to start designing your own caps: blank vial cap

I thought it would be a fun project to try and build the heater PCB by hand, but I ran into some problems. Even without a BOM, I was able to procure most of the components by looking at the schematic, apart from the two metal spacers. I tried to measure them (3mm height, 4.8mm diameter, M2.5 thread?) but I’m not sure where to buy them?

As the gerbers are available it was easy to make the PCB, but as there’s no CPL file (Component Placement List), and the silkscreen does not have the component references either, I’m not entirely sure where each component should be placed. I guess I could try to reverse-engineer it from the gerbers and the schematic, but thought I’d ask first! :slight_smile:

I was wondering whether you had considered publishing the source files? That would make it easier to contribute improvements to the designs, whereas with just a PDF of the schematic and the gerbers we would mostly just be able to manufacture the design.

I was also not sure what the intended open-source license is, as the schematic PDF only says “OPEN SOURCE - FREE TO DISTRIBUTE” and I couldn’t find any license files in the repo.

Ah good points, thanks @gendor for asking about this. We clearly need to fill in these details (especially the missing license!) Let me talk to the team and report back early next week.
