Tháp đo nhiệt độ (Temperature Tower) nhỏ nhất thế giới

Are you sick and tired of wasting so much filament on a regular-sized temperature tower? Are you receiving an Alien3D sample filament pack each month, and are only allotted so much filament to play with? Do you need to see if your 3D printer is well calibrated for tiny prints? Are you in a hurry and need a calibration test done in under half an hour? There's gotta be a better way!

Well, let me introduce the world's smallest temperature calibration test! Code name Ingenious Armour in Tinkercad! No longer do you have to spend more than a meter of filament on calibrating your 3D printer! 

Made in Tinkercad. My first model, so be gentle! I included a picture of it next to a normal, 100% scale, benchy boat!

Enjoy!

EDIT: I added a model with A/B/C/D instead of temperatures in case if you wanted to use different temperatures. Thanks to zsmith35 for the great idea!
