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. B01-1: Barb connector with male thread : This component is valuable when users choose to create a DIY waste bottle by repurposing plastic buffer bottles commonly found in laboratories. In such cases, two holes with a diameter of 13 mm-14 mm need to be drilled into the bottle cap to accommodate the barb connector, which is secured using the B01-2 hex nut from the inside of the cap. To achieve an airtight seal, hot-melt adhesive or Parafilm can be applied at the interface of the connector and the cap.
2. B01-2: Barb connector hex nut
3. B02: Extension tube: The extension tube is an integral part of the barb assembly on the inlet side. Its primary function is to maintain a height differential between the waste inlet and the vacuum outlet, and thus prevent liquid ingress into the dry zone of the apparatus. This component can be easily attached by screwing it onto either B01-1 or G02.
4. B03: Two-headed barb connector: The two-headed barb connector is designed to extend two shorter silicone tubes.
5.
