Teach your students how to model simple 3d objects, and neatly tuck away the myriad cords tangling on the floor, both at the same time!
The base is a sketched rectangle, with the bottom line switched to construction mode; then a circle is added of arbitrary radius tangent to the bottom, also in construction mode. To that add a non-construction arc of angle 180 touching the construction circle and two lines of equal length connecting it to the bottom line, then two lines connecting those bottoms to the original rectangle's corners. Constrain the distance from the left and top arbitrarily (I ran a line from the centerpoint of the arc to the top of the arc and then from that point to touching the top line of the original rectangle, but there's probably a better way), pad to an arbitrary width, then rotate the view to the top and sketch a hole centered in the side without a tunnel going through it. Punch that hole through, then fillet and chamfer to taste.
For Clip 2, add to the original rectangle before making the original "right" line a construction line, then repeat much of the original process to add a second "tunnel". Remember to fully constrain your sketch!
Students will learn how to 3d print useful primitive objects, and your classroom will be tidy and safer from trip hazards
Elementary students with a rudementary knowledge of computers should be able to do this with some effort - when I was in 5th grade I had to memorize all 50 states and their capitals, as well as draw it on a blank map, so this seems easier.
Flag all cords that are not properly anchored but that do not require slack to operate (you might want to anchor the projector's cord but not the laptop or mouse's cord); check with school maintenance for what size anchoring hardware they prefer to use (they might need a bigger mounting hole). Accurate measurement tools will also be necessary - if calipers are not available, they can be printed from this site (flat, soft, and non-conductive calipers are safest!)
- Give each student, or group of students, a set of cords to anchor and any other requirements.
- The students then model the clip
- Students work with the teacher to print the clip
- Maintenance then installs the clip
See Objectives - your students learn how to make clips, and your classroom gets tidier and safer. For grading, you could do this quite early in the year and deduct points if any of the clips fail by the year's end.
