MAKITA to FERM Drill adapter

This is an adapter that allows you to use a Makita-style battery (Chinese copy) with FERM power tools. It’s a simple and practical way to reuse batteries you already have for different tools. The adapter is designed for the common 18V Makita clone battery and fits FERM cordless tools securely. It has reinforced walls for better durability and can be printed easily. There are openings for cables and mounting holes. For printing, PETG is recommended for strength and temperature resistance. A layer height of 0.2 mm works well, with at least 20% infill and three perimeters. Please note that the contacts and wiring are not included in the model. You will need to add your own metal connectors and contacts. Be sure to check the polarity and voltage before connecting the adapter to your tool.
