Compression spring - 90N

A working spring that generates about 90N (can hold 9kg) at solid length (without cracks or damages). Fatigue test has been performed up to about 4000 cycles without any damage (decay within admissible range of 5%). However according to calculation, it should have infinite life (engineering speaking).

⚠ ATTENTION ⚠
This spring is designed taking into account mechanical properties of PLA+. Any different material or setup will impact the declared performances.

☝ Do not scale the model. Any dimension change would impact performances and resistance.
✌ Print with 100% infill (layer height no more than 0.2mm). Printing direction is vertical with supports between coils. They will be easy to remove.
🤙 Make sure your printer is well tuned and you get proper layer adhesion.

📚I won't be explaining the whole design process that guarantees functionality and performances, but if you are interested you can contact me.

Also, if you need a specific spring of specific load, do not scale the following one cause it won't work. Spring has to be designed accordingly.

Data of the current spring:
Free length = 100mm
Outer diameter = 50mm
Inner diameter = 30mm
Solid length = 69mm ca.
Max force @solid length = 90N ca.

Extension spring 100N.stl

Extension spring capable of exerting a max force of about 10kg. In order to achieve this spring shall be post processed with annealing.
If this is not done, max allowed deflection and force would be about 6kg.
Please refer to README file for complete data and instructions.

Sharing something about my homeland ☺️

The **pumo** is a** traditional decorative element** from my region, Apulia, which symbolizes **spring** 🌼

Its shape resembles that of a **bud**, ready to **bloom**, with the auspicious meaning of **fertility, wealth and good omen** for future events.

To bring luck, wealth and prosperity, however, the pumo must be given as a gift. In fact, it's often chosen as party favors on several occasions.

In this case, I hope you like and would accept them as my gift for you!

Hope you'll enjoy printing these models and add them to your decorations and also, why not, gift them to your friends, relatives and everyone else you would like to ☺️
