IPA Bottle Anti-Waste cap

So i had this issue with my IPA bottle. When i want to pour a little bit on a cloth or on my printbed, a lot of Alcohol comes out.So i designed this little cap with small holes that you can put inside the bottle opening to prevent spilling or wasting a unneccesary amount of fluid.the inside bottle diameter is 21mm.If you have any suggestions, feel free to share them!you can also make a better version, but please tag me in it! (and yes, i know my phone camera is shit XD)
