Simple Seismometer model for STEM education

Description:

This Simple Seismometer mode is intended for STEM Education is a 3D-printable model designed for easy assembly, featuring only snap-in-place, 3D-printable components that don't require adhesives or complex tools. It provides a hands-on introduction to seismology, allowing to explore fundamental earthquake detection principles in a tangible way.

Created as an entry for a 3D design contest, this model is my first self-made design, built with accessibility and practicality in mind. It encourages curiosity about earth sciences, physics, and engineering. Designed for learning purposes only, this model is not intended for real-world seismic measurement but serves as an engaging way to explore the basics of how seismometers work.

Assembly Guide:
Very straightforward & easy: Snap the “paper retainers” as well as one “paper roll retainer” to “tray”. Put the “extension arm” onto the “main rod”. Lead the spring close to the holes and secure with the little printable stand-offs. Clip paper to ~5cm strips, tape the strips together and feed onto the “paper roll holder”. Allign the second “retainer” with the ”roll holder” & snap to the tray. Feed the paper through the retainers and that's it!

Use guide: 

1. Secure the Seismometer - Place the model on a stable surface and ensure it is firmly held or fixed in place.
2. Insert Paper – Slide a strip of paper under the recording arm.
3. Simulate an Earthquake – Shake the surface while gently pulling the paper to record the movement.
4. Observe the Results – The pen or pointer will leave a trace, representing simulated seismic activity.

5. Look at the recorded lines and ask:

   How do the lines change with different shaking intensities?

   What happens when you shake in different directions?

   How does this compare to real earthquake recordings?

Misc: 

Printing Profiles: Currently unoptimised for TIME. I have separated models to minimise risk of print failure, this increases time but it's better to get the print right first time instead of having to reprint! I have saved profiles that I used to print all the components for my model within the .3mf file. Just look for the print profiles that correspond to the build plates! :) (P.S: I am new to this so a lot of it will be janky.)

Currently released as V1.0

Future plans: Ballast weight (could be a holder for an AA battery, as long as it weighs the pen down), Hinged/ Free-mounted lever arm for more & easier graphing movement, Spring-loaded pen/ pencil retainer
This is my first model so feedback is appreciated!

Cheers!
