Help tools for laser distance measuring corners of rooms.
Warning! if your doing a basic floor plane, don't do this! Measure the width / length and move on with your life.
If any of the following conditions apply to you:
- Your rooms are not remotely square and your trying to measure the angles.
- Your chasing measurement problems and nothing is adding up.
- Your overly precise in your work. Like waaaay overly precise.
- Your looking for an excuse to buy a laser distance measure.
Then this might be the rabbit hole for you!
Hand Held Laser Distance Measure:
- Look for one with a tripod mount screw hole in the bottom.
- I'm using a Stanley TLM300.
Hex Bolt - 1/4-20 x 3/4" L:
- Only needed if your laser has a mounting screw hole.
Wooden Dowel Rod - 3/8" x 3' or 10mm x 1M:
Nothing special. I was using .15 layer height, .4 nozzle, 20% infill. PLA works great.
If your laser has a tripod mount screw hole:
- Insert the 1/4"-20 screw into the Mount Knob.
- Screw the Base onto the bottom of your laser.
Otherwise rubber band the Base to the laser or modify the model to suit.
Insert the dowel rods into the bottom of the two targets.
The radius on the rear of the laser and on the targets are both 1" (25.4mm). The radius is put into a corner and made tangent to the two walls. By measuring the distance between the center of the radius's, you can define where the walls are. When you measure the four sides of a box and the two diagonals, you fully define all the length and angles of the box. Only one diagonal length is required, but the other gives you a verification to know your measurements are good.
Place the corner target into a corner you want to measure and align flat face to opposite corner.
Place the laser into the opposite corner. Line up the laser to the target and measure distance.
Draw a simple field note and write down your measurements.
Repeat so you have measured 6 distances for a box. The 4 sides and 2 diagonals.
With your measurements, you could trig the angles by hand, or you can use any CAD program and draw out your results.
The Corner Target is sometimes useful, just remember your measuring to the edge and not to the center. The layout needs to reflect that
