Saw this on BV3D: Bryan Vines's "3D Printed Dad Jokes That Will Make You Laugh Out Loud!" YouTube video recently and was going to print it out however the one on Thingiverse by Forks was in low poly rez so I decided to recreate it in F360 and make my own as it looked like a quick whip-up. Did two versions a tall and a short one and so far they have printed out great for me (I did use organic supports for the rungs) and should fit a Lab sample jar without any resizing. These could also be printed out for your child's dollhouse even or resize it and print it large enough to sit on.
