Bosch 18v to Ryobi 18v adapter

thingiverse

This is a slightly modified version of Simhopps adapter. I beefed up the side walls as his version broke after a month or two of use. This is much stronger, but retains all of the original functionality and looks. update: Ive been using this for 18 months with no issues. Some have asked about where to get the metal for this adapter. I just scavenged some broken Ryobi 18v batteries, (which can be purchased from ebay for less than $10) but you can also fabricate fairly easy.
