1. A fluid delivery system comprising:
a motor configured to provide rotational motion about a first axis to an eccentric at a non-central location on the eccentric such that the eccentric rotates eccentrically about the first axis;
a rotary component having a first end and a second end, the first end having a first rolling bearing configured to receive the eccentric the second end having a first bore and a second bore, wherein the first bore and the second bore are configured to secure a pin;
an alignment mechanism comprising:
a housing comprising a first housing portion and a second housing portion separable from the first housing portion, the first housing portion having a first slot and the second housing portion having a second slot;
a first roller configured to be disposed within and move along a length of the first slot, the first roller having a first receiving portion;
a second roller configured to be disposed within and move along a length of the second slot, the second roller having a second receiving portion;
a pin having a first end and a second end, the first end configured to be inserted through the first bore and into the first receiving portion of the first roller and engage the first roller, the second end configured to be inserted through the second bore and into the second receiving portion of the second roller and engage the second roller, such that the pin can rotate while engaged with the first roller and the second roller; and
a coupler comprising:
a second rolling bearing configured t receive the pin to movably couple the coupler to the pin, such that the pin extends through the coupler and the rotary component to detachably couple the coupler to the rotary component; and
a receiving slot configured to receive a reciprocating component to moveably couple the reciprocating component to the coupler, the reciprocating component configured to reciprocate in a second axis transverse to the first axis and to move in the receiving slot along a third axis transverse to the second axis; and
wherein the coupler is configured to move along the pin, in a fourth axis transverse to the third axis, between the first bore and the second bore of the rotary component.
