Ryobi One+ to Black And Decker Battery Adapter

A modified Ryobi One+ to Black and Decker battery adapter. Useful for using ryobi Li-Ion batteries in your old B&D weed-eater. I started with the FreeCAD design by "sucka" and made some minor alterations to make the walls thicker and change the way that battery contacts are made.

v10 9/24/2018 - I made some adjustments to V9 to reinforce the area where the contact screws hold the brass contacts. My original stripped the thin plastic. I cut a small recess so that the B&D release would travel down far enough to release easily. I added a small retention for the spring.

NOTE: This particular version will work on the drill and maybe the weed eater. I know that it does not work on the dust buster vacuum or the leaf blower. I am working on versions for those.

Notes:

Post-Printing

1. Clean up the support
2. Use a 3 inch long piece of 1/4" brass stock. Wrap the middle around a pencil to make a "lollipop". Flatten the lollipop into a "Z" like shape for the contacts. See the pictures for an example.
3. Insert the custom contacts into the slots in the printed part and use a 4mm (approx) diameter bolt to hold the contacts in place. I also use the bolt to hold a ring connector to make the connection to the Black and Decker battery contacts

NOTE: In one case, when I pushed the Ryobi battery into the adapter, the brass contact was bent upwards and did not make contact. Make sure that the contact is centered and adjusted to make contact.

How I Designed This

I used the EXCELLENT files from Ryobi One+ to Black And Decker Single Source Battery Adapter by sucka May 13, 2015. There were some minor issues with a small hole in the base and the walls were too thin. I also made some adjustments to the slots for the Ryobi connectors and added the holes for a hold down bolt.
