Squeeze-bulb tesla valve duster

This is a squeeze-bulb with a tesla valve for faster refilling. I took the idea from a comment in the latest video of clough42 where he makes a one way valve with a bb pellet, this is print in place and needs no extra mechanisms. It works well as a proof of concept but could be improved. Thera are some loses and doubling the amount of tesla valve pockets would help with a double layer. Here is the onshape link if someone wants to improve it :)https://cad.onshape.com/documents/b505d4d6cbfd7f8c9edeb344/w/45808b00cfc2b139f04b3cc8/e/0fbb58184893e34d7e1cac18?renderMode=0&uiState=66df41a8492a15235b74fe5f
