(SEE UPDATE AT BOTTOM) For Realtors, open houses are common. When presenting an open house, pointer signs are often placed at street corners to help direct people to the available home.

What I've found annoying is that if I want to put the date and time, I normally strip any previous date and time on the sign (usually held to the sign by packing tape), then print the current info (to keep it readable) and tape it to the sign. This is time-consuming, wasteful, annoying, and will often damage the finish of the sign.

So I designed this lettering system. I created a carrier plate for each side of the sign that's permanently mounted to the sign using mounting tape. I then created tiles for the days of the week, and some basic numbers and punctuation for the time. Finally, I designed a very simple way to lock the tiles in place so they won't fall out of the carrier. This is very much like the plastic name tags for offices from the 60's (the white-lettering-on-black-background plastic plates that you'd slide into a metal tray on the wall).

I designed these at 144 pt (2" tall) so they could be read from at least 20' away, and as people drove by. The trays can be scaled up or down on the X-axis, or multiple trays can be butted together - I kept the ends simple in case larger sizes were needed.

I printed these in PLA. ASA would probably be a better choice, but since the signs are outside for a maximum of a day or two, and usually shorter, I don't think UV exposure is a thing.

The wedge is used to lock the tiles in place. It's pretty simple: just slide one wedge underneath each end tile. It doesn't have to be slammed in, just enough to feel some resistance. When you're done, and especially if you're using PLA, I would remove the wedge and tiles. If you leave the wedge in place, PLA can deform under pressure over the longer term.

UPDATE:
If you're using my Open House lettering set, I've just updated with some additional pieces:

- Carrier Extension (in case you need to add to the length of the holder)

- TODAY (extra word)

- NOW! (extra word)

- Half Spacer (helps with the longer words)

- Full Spacer

Enjoy!
