This is my make-through for the week's assignment. Cover well it's freezing!

This week we began to deal with manufacturing techniques as in 3d printing, laser cutting, and milling, and with assembly needs like snap fits.
I have dealt with snap fits before as designing a 3d printed Arduino case enclosure for the wall plotter and dealt a lot with press fits but the snap-fits are more efficient than press fits .
Get Ready for it!
Intro on snap-fits
Intro on snap-fits
Wikipedia: A snap-fit is an assembly method used to attach flexible parts, usually plastic, to form the final product by pushing the parts' interlocking components together. There are a number of variations in snap-fits, including cantilever, torsional and annular. Snap-fits, as integral attachment features, are an alternative to assembly using nails or screws and have the advantages of speed and no loose parts. Snap-fit connectors can be found in everyday products such as battery compartment lids, snap fasteners, and pens
Now we know that it is very important in our life.
What we will focus on this week is to make an enclosure using snap-fits, and the first step is to know the snap-fits types
Well, those are the most common, they can be used in plastics, wood, or even some metals!
what we will focus on is that used for 3d printing plastics and laser-cut wood
I will not dive deep into this as our instructors already made a great job on this.
Our mission this week is to make an enclosure for a commercial product.
I chose the car remote keychain and the electronic finger counter
I will try to use at least 2 types of snap fits
the first one for the enclosure itself and the other for the batteries' cover
As they are just small parts we will only use 3d printing

car remote Keychain
Starting with the keychain
Using fusion360 for the first time
It was HELL!
I am good with solidworks but when it comes to fusion I act like a duck!
Anyway, the first thing that I did that I searched for a ready PCB for the car keychain, and I found one on GrabCad
It sounded to be easy until I spent 10 hours trying to use fusion360
I had trouble doing every feature!
Problems come from NoWhere
but I managed to reach a good result ( or that what I thought )
that was an easy 6 grams!
Print that dude and we finished!
damn a big stupid mistake!
the snap fits looks in one direction! that means it is useless!
finger counter
finger counter
That is it for fusion, I will not use it anymore
Time for solidworks!
The finger counter have two buttons one for counting and the other for reset function, a small LCD shows counting number, and a small battery
We will not duplicate the existing commercial version, we will make some adjustments for a removable battery
We will use full perimeter snap-fit for the main enclosure and screw joint for the battery cover
Now, It is time to print
Another 6 gm to GO
HINT: white is not the best color to print with, it became dirty in 5 min!
CONCLUSION
CONCLUSION
that week I learned how to make snap-fits and screw-joints, although it was not my first! but this time I do it with science
