Bottle Transfer Caps 2.0

This is version 2.0 of my original Bottle Transfer Caps IMPROVEMENTSIncreased size of inlet to allow for a faster flowadded air vents so the bottom (full) bottle can let air escape These caps are meant for bottles holding soaps, lotions, and shampoos. They will also fit some food bottles (like ketchup, mustard, etc), however be cautious using 3D prints for food. Three sizes are included that fit most standard (USA and others) bottle sizes. The LARGE model will fit large shampoo/conditioner bottles. The SMALL model will fit small hand washing soaps. The MEDIUM, of course, will fit the ones in between. HOW TO USE There are 2 sides to the cap. A funnel side, and a spout side (See photos). The idea is to take an almost empty bottle and transfer it to another bottle. The old (top) bottle is attached to the funnel side, and the new (bottom) bottle is attached to the spout side. Poke or cut a hole in the old bottle to stop a vacuum forming. The bottom bottle releases air through the vent hole
