Makerworld has significantly reduced the download/print points awarded to designers. Instead, they have introduced the "Boost" token, which you can apply to models that may not be the most popular (already gaining points from downloads and prints), but are useful or meaningful to you in general. This supports and encourages us, the "losers" (those not focusing on popular themes like Star Wars, car keychains, countless airless balls, etc.), to create more useful or niche designs.

As a biologist focusing on biomedical science, particularly in gene therapies for monogenetic diseases, I enjoy exploring 3D printing as a hobby. I've recently developed an affordable 3D printed liquid aspiration unit for laboratory use, aimed at efficiently removing supernatant from biological samples. I'm pleased to share that these designs have been published in the peer reviewed scientific journal HardwareX, contributing to the accessibility and affordability of laboratory equipment for research. It’s a open access journal, therefore no paywall barrier, you can read the article here https://www.hardware-x.com/article/S2468-0672(24)00003-8/fulltext

This page holds the following models described in the article.

1. SC01: Single channel nozzle: The single-channel nozzle is compatible with most 200 µL and 1000 µL micropipette tips, directly connecting to the silicone tube. It attaches securely to the M01-1 main unit and comes into direct contact with liquid waste.
2. SC02-1: Single-channel nozzle 1000 µL tip ejector arm: The single-channel nozzle 1000 µL tip ejector arm is connected to the SC02-2 component by a snap-fit design to create a cohesive ejection unit for removal of 1000 µL micropipette tips from the SC01 nozzle.
3. SC02-2: Single-channel nozzle 1000 µL tip ejector
4. SC03-1: Single-channel nozzle 200 µL tip ejector arm: The single-channel nozzle 200 µL tip ejector arm connected to the SC03-2 component by snap-fit to create a cohesive ejecting unit for removal of 200 µL micropipette tips from the SC01 nozzle.
5. SC03-2: Single-channel nozzle 200 µL tip ejector
