Christmas Light holders for exterior.

thingiverse

I've always dreamed of having a perfect row of Christmas lights where guttering isn't an issue. Check out the before-and-after photo on one edge. The first time you install them, you'll have to staple as you go, putting up the lights. After the holiday season is over, simply pull down the lights and leave the mounts in place; next year just push them in, saving time while achieving a fantastic look. I've upgraded from version 01 to version 02, incorporating a wider edge for faster stapling using a staple gun. I've also revised the orientation to create a stronger grip. The original configuration sometimes caused the light base to split if it fit too tightly; this new design works perfectly. I printed with 20% infill and it's plenty strong now. Instructions Print at 10% infill, using three layers for extra safety - I did that for peace of mind. Two might work for you though.
