Ryobi 18V Battery Connector

This Ryobi 18V Battery Adapter makes it possible to power any device or tool with a Ryobi 18V Battery. This adapter can be used as the basis of an adapter to power non-Ryobi tools or to power electronic projects with Ryobi batteries. I am using this adapter to power single-board computers and a planned mobile robot. Update 3-7-2020: I added photos of a portable radio that I converted to use Ryobi 18V Batteries. This is an example of how this adapter can be used. I also added a version without mounting ears. Here's a video showing the completed Ryobi Battery Adapter: https://youtu.be/abT4txqD0Zs I took the original design and enhanced it by adding mounting tabs, improved latching for the battery into its holder, and redesigned the tower to use Keystone 209 contacts. This new adapter now clicks the battery into place securely and features a mechanism to lock the battery contacts in place without sliding up. For the contacts, search for "Keystone 209" on Amazon or EBay. One supplier is: https://www.amazon.com/KEYSTONE-209-BATTERY-CONTACT-pieces/dp/B00LPOVJHS I recommend printing the parts at 75% fill and 0.1 mm layers using PLA. Use supports around the base clip points. Before installing the Keystone 209 contacts, compress them slightly with a pair of pliers for a perfect fit (see photo). Solder your wires onto the battery tabs before sliding them into the tower pockets to avoid damaging the plastic. Install the contacts by pressing them over the pockets until they lock into place. Assemble the base and tower using either 4 mm or 6-32 flat head screws and matching nuts. I plan to use high-efficiency DC-DC converters to generate 5V, 12V, and 9V from the Ryobi 18V battery.
