This is a handy 3D printed adapter designed to fit standard USB rechargeable automatic water pumps onto smaller 5-Liter and 10-Liter water bottles.

Most automatic water pumps found on the market are designed exclusively for large 19L/5-Gallon water jugs which have a 55mm neck diameter. However, in many countries, 5L and 10L bottles use a standard 48mm neck finish. This adapter bridges that gap perfectly!

Features

• Perfect Fit: Adapts a 48mm bottle neck to a 55mm pump base.
• Stable Design: Prevents the pump from wobbling or tilting while dispensing water.
• Easy to Use: Just screw or snap it onto your 5L/10L bottle, then place your automatic pump on top.
• No Supports Needed: Optimized for easy 3D printing.

🛠️ 3D Printing Settings

• Material: PLA, PETG, or Food-Safe Filament (PETG recommended for kitchen environments).
• Infill: 15% - 20% (Gyroid or Grid)
• Layer Height: 0.2mm
• Supports: No supports required if printed in the correct orientation (flat side on the bed).
