For the fourth week we 3D printed the pieces that we needed to control the translation motion.
The 3D printing was messy for the gears, the reason was that the gears were really tiny, less than 8 tooths.

This part is for the Ballast System

Here is the gear nested in the axle, this will be attached to the 24teeth_Gear.

Now that we have the gears and the axle we can 3D print the rails to pilot the moving part of the syringe.

The gears will be translated to the rails.

If you have the occasion, maybe, try with a resin printer and not a 3D printing for the little pieces

( Go to the files and open : Rail1_Syringe.STL , Rail2_Syringe.STL Axle_Syringe.STL, Gear_24Tooth.STL, Gear8_Tooth.STL)

For the next week we will have to make a list of the electronics component and 3D printing the worm drive
