Updated: Version 2 of the cold adapter. Widened the counter sink hole. Might fit tap better.

Remix of ksaathoff faucet handle adapter (https://www.thingiverse.com/thing:334944)
Remix is a replacement of Moen 97556 (can find on amazon, no picture on moen site)

This has been modified with the following:

• 1mm take off the stopper on the bottom (tap wasn't fully turning off)
• Shaved some height off the vertical struts to fit the tap better.
• Removed a high ridge on the inside so the adapter sits more flushed.
• Created slant on vertical struts.
