Say goodbye to unleveled picture hanging. Using a rounded french cleat design you can easily rotate your artwork without having to add holes in your wall.
Speaking of holes, this new design uses an angled t-pin which you can pick up from any hobby store or Walmart for a very low price. The angled pin is inspired by the super strong OOK Professional Picture Hangers which I have used to hang items as heavy as a large dresser mirror on drywall without studs and almost no mark in the wall. Nails are messy and leave such a large blemish on your wall. See the included pictures where I replaced the old version of the hanger, which used small nails, with the t-pin. The mark left behind is nearly invisible and very easy to patch when desired.
The previous version I made worked but the back was weak and tended to snap off. Plus I was thinking old world and not embracing what 3D printing could do. I completely redesigned the Picture Frame Hanger to use this new Curved French Cleat design. Designed to print flat with no supports the back is very strong and will no longer snap off. You may want to apply a bit of sticky to the part which connects to the back of your canvas print to help hold it in place as you lower it on to the wall mount. The curved design not only allows you to reposition but also keeps the picture from sliding off to either side.
