for filling my small Isopropanol spray bottles (re-used from other products) from my 5 ltr Isopropanol bottle I needed a small funnel.

One with the marking "Isopropanol" so you do not use it for anything else and the other one just blank.

Happy printing.PS: prints without support (at least in Bambu Studio)
