Height tracker

It's always hard to find the right object to measure your kid's height against the edge of a door accurately. I've used books, random boxes etc. but they were always a bit of a struggle to hold the object and scribe a line on the door at the proper height.
I made this so the process is easier. Have your growing kid stand with their back against the edge of the door and slide this down the edge until it contacts the top of their head. Draw a line and write the date. Simple!
Have fun and remember: Your kids grow up way too fast.

I printed this in PLA with a 0.3mm layer height with 5% infill. Nothing special about it.
