Assessing Community Interest in Affordable 3D-printed Tools for C. elegans Research

After recently submitting a paper where I developed and optimized 3D-printed tools for my C. elegans research, I want to know if the community would like a one-stop shop for affordable tools to help with their research! I hope to use this feedback as part of a fellowship proposal for designing marketable products that translate from research to business/services.
1.What types of C. elegans research do you do?
2.Do you have any current and/or future C. elegans research questions/projects that could be more easily performed with the assistance of custom 3D printed tools?
3.How interested would you be in buying affordable 3D printed tools to assist in C. elegans research?
4.Does the following pricing system incentivize you to purchase 3D-printed models and tools for academic research using C. elegans:

$1-$5 USD for a one-time download of an .STL file for unlimited printing with your own 3D-printer.

$1-$5 USD + price of materials + shipping for ordering a tool(s) and requesting that we produce it on-site with our 3D-printers, and transport it to you? (materials typically $0.02-$0.05 USD per gram of resin used)
5.Would you be interested in requesting custom models and collaborating to improve the design for your needs?
6.How would you feel about commercializing a product that was deigned out of collaboration with your lab?
