I teach electronics at a highschool level  - in our workshop we have 2 Proxxon tmb 220 mini drill presses, which are excellent for drilling PCBs but the dust gets all over the place.So I designed this solution that splits a vacum hose into two 3/4 " garden hoses which is held in place right where the dust is generated.Printed with 100% infill to make sure it lasts in a workshop environment with students. The hose guide rings needs some support.Designed in tinkercad - all files are here: https://www.tinkercad.com/users/ev4MMzGq1Oz-mn-t
