Borderless replaceable photo/print wall mount

This is a very simple borderless/invisible mount for photos.  Works well in a grid or as a series of photos.

The model comes in two parts:

1. A thin wedge bracket (like a vertical french-cleat) that attaches to the wall with a command strip (part: 17023)
2. A sqare mount that the picture is glued to (3m double sided tape: 9088 works well)

To use:

1. Print model
2. Print picture square larger than 140x140mm
3. Trim picture (makes it easier to align)
4. Fix command strip to the bracket, so the removal tag is sticking out from the curved end.  Put the command strip on the same side as the spacer block on the bracket
5. Put tape on the mount part.  3-4 strips horizontally works well for me to prevent sagging
6. DOUBLE CHECK THE ROTATION OF THE MOUNT (the slot for the bracket must be pointing down, or your picture will be sideways/upside-down!)
7. Press picture onto tape firmly
8. Turn mount upside down, and trim along edges with a sharp knife, holding mount firmly
9. Fix bracket to wall
10. Slide mount onto bracket
11. Stand back and admire.

To replace photo:

1. Print the mount only
2. Attach photo to th new mount
3. Slide old mount off the bracket
4. Slide new mount off the bracket
5. Stand back and enjoy a new image

To remove entirely:

1. Slide mount off bracket
2. press bracket firmly against wall
3. Pull the command strip tab string up (pull it along the wall, not away from wall)
4. Once command strip is as pulled as possible, gently remove bracket from wall

Different picture sizes:

The model is very simple, it should be trivial to adjust for different picture sizes.  The bracket and bracket groove are sized to fit the command strips, so ideally scale the edges of the mount part only.   It's a good idea to make the mount several mm smaller than the print size of the picture, to make it easier to align when mounting.
