Bosch 18v to Ryobi 18v adapter

thingiverse

This is a modified version of Simhop's adapter that I've strengthened by beefing up the side walls, which were prone to breaking after about a month or two of use. The result is an even more robust design without sacrificing any of the original functionality or aesthetic appeal. Update: I've been using this adapted version for 18 months now with no problems whatsoever. Some people have inquired about where to source the metal for this adapter, and I can tell you that I simply salvaged some scraps from broken Ryobi 18v batteries. These batteries can be purchased on eBay for under $10 if you don't happen to have any lying around. Alternatively, fabricating your own metal components is relatively easy.
