We put the ramp attached to the blocker and the 3D printer frame against the wheel. We then put in some pipette tips into the wheel and rotated the wheel using the DC motor. We achieved remarkably successful results, with many tips sliding into the ramp in the correct orientation as desired. Success is sweet. … Continue reading Wheel + Funnel + Ramp

We set-up the ramp and the blocker and tested it by sliding a few pipette tips down. It was successful. Testing the new ramp and blocker.

We reprinted the ramp slices with the holes to attach them to the 3D printer frame already built in so we don’t need to drill the holes manually. Design of new ramp with holes at the bottom. (Credits: KK) Circling back to our idea for a blocker on 01/07, we also designed a blocker at … Continue reading New ramp design

We realised that we needed to be able to adjust the width of the gap between the ramp slices. Hence, we drilled holes into our ramp and attached them to a 3D printer frame using screws. Then, we slid some pipette tips down the ramp to test it. Drilling holes into our ramp slices to … Continue reading Drilling into the ramp

We tested our new ramp, and it seems to be working with the addition of masking tape at the end of it. Our new ramp.

Upon fiddling with the motion of the wheel, we discovered that some pipette tips don’t fall from the top of the wheel. Additionally, some pipette tips get stuck in the hole of the funnel. To circumvent these problems, we designed and 3D printed new holders for the wheel as well as a new funnel. Our … Continue reading Improvement of the blockers attached to the wheel

We noticed that after the pipette tips fall into the ramp, they would not stay in the ramp and would slide out of the ramp. To circumvent this problem, we decided to add a blocker at the end of the ramp instead of making the ramp longer, which would make our prototype unnecessarily long. We … Continue reading Creation of the ramp blocker idea
