Vacuum hand pump adapter screw

Always grabbing my vacuum cleaner, no way. I couldn't find a adapter for the handpump I already had. So I made one that you can use for ziplock/filament bags with a screw cap. Simply screw the adapter on your bag, then place you handpump in the adapter and you are ready to get the air out. 

I like the longer/taller one better. It fits better. But both work fine. 
 

I printed it in PLA. you can use it on this bag; https://www.amazon.nl/dp/B0DMP9714K?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
