Trumpet practicing tool for San Jose CA schools

Want to help me lower the barrier to better trumpet education by giving FREE practice tools to all trumpet students in San Jose? These tools, when made from metal, cost between $50-$70. I'm raising money to benefit Public Middle and High Schools in San Jose, CA by lowering that cost to FREE. Hacker Dojo, is providing the facility, TAZ Lulzbot 6  3D printer, access time, space to organize for each school, and also tools to adjust each Embouchere Visualizer by hand.  I will be buying the 3D PLA 3.00 filament in all colors for this project, and donating my time over the summer to make this a reality for EVERY trumpet student in San Jose, CA!  Any donation will help make an impact. I am a trumpet teacher/brass coach in the Public Schools in San Jose and strive for equal education and access for all. 

Printer filament is $24.99- I plan to buy $500 of filament for this project.
Hacker Dojo Membership is $150 a month, the space will be required May, July, August. $500 for facility with equipment.
