Pill Dispenser Full Assembly

The full assembly of the project. It's in STEP format so it can be modified by everyone.

Mechanism V2 STEP

This is a STEP (editable) file of the new mechanism. It uses small stepper mottors to rotate the wheel. The wheel must be changed for each size of pill.

Mechasnism V2.1 STEP

This is a STEP (editable) file of the new mechanism. It uses small stepper mottors to rotate the wheel. The wheel must be changed for each size of pill.

PS: Is slighlty bigger than the last one.

Small Wheel STEP

The wheel of mechanism must be edited dependign on the size of the pill you want to disepense. This version is for a small pill.

It is held in place with an M3 screw.

Large Wheel STEP

The wheel of mechanism must be edited dependign on the size of the pill you want to disepense. This wheel is prepared for larger pills such us "ibuprofen".

It is held in place with an M3 screw.
