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. MC01-1: 8-channel nozzles: The 8-channel nozzle unit is equipped with nozzles spaced to accommodate a standard 96-well plate, enabling the simultaneous removal of liquid waste. These nozzles are compatible with most 200 µL micropipette tips. The unit is designed for use with the MC01-2 connector for attachment to the M01-1.
2. MC01-2: M01-1 8-channel nozzles and MC01-1 handheld unit connector: This connector joins both the MC01-1 8-channel unit and the M01-1 main unit. Additionally, it also connects to the silicone vacuum tube.
3. MC02-1: 8-channel nozzle tip ejector arm: The 8-channel nozzle tip ejector arm is connected to the MC02-2 by snap-fit to form an ejecting unit designed to simultaneously eject eight 200 µL micropipette tips from the MC01-1 nozzles.
4. MC02-2: 8-channel nozzle tip ejector
