Universal Prototyping Kit for

  • We built a prototype frame from UPK case for Nimble to fit into a waterproof case (some Pelican clone from Italy).
  • The UPK uses 20 mm as a grid size while Nimble is around 14 mm so it took a little bit of tricks to get them to fit together. The UPK frame inside the box, still needs some fixing points and ‘buffers/dampening’ to keep it safe during travels. Here’s an example to some MacGuyvering, where the T-slot on the bottom is adjustable and allows the perpendicular T-slot to rest ontop of it. This T-slot is fixed to the racks, which isn’t perfect, but allows for the racks to be removed from the box in a pretty simple way.

The parametric racks would make it even faster and easier.



What did you accomplish?

We made a prototype alternative frame for Nimble using UPK. It still requires 3d-printed frames for the electronic housings, so in a way, all we did was replace the 14mm plastic T-frame clone with the real one. The benefit is that it’s a bit more rhobust/weather proof and can help make the assembly much faster - assuming the parts haven’t been printed in advance.

Next steps

What needs do be done after this hackathon?

  • Finish the freecad 3D model and assembly instructions.
  • Make it look as good as Nimble.

Open questions

UPK seems to be good for rapid prototyping but the parts are (relatively) expensive to be used permanently compared to ABS/PETG or alternatives like wood or sheet metal. So is this a viable solution, even though it looks cool?
