LEGO Wrapping Paper Cutter Presents Machine
The hardest part about wrapping presents may be actually cutting the rolls of paper into perfect sheets, that is unless…you’re using this innovative machine by The Brick Wall. Simply put, this innovative machine precisely measures the presents by scanning it and then determines exactly how much paper to cut, which means you probably won’t be left with random shreds after you’re done wrapping. Read more to see it in-action.



It’s not the most complex machine, as the cutter itself measures 45-inches, while it’s controlled with an EV3 brick and runs on custom software coded in the Python programming language. Boxed presents are set on a separate area where two optical sensors scan and calculate its dimensions. The Python software then calculates the total volume of the box and then determines the exact size sheet needed to cover everything, complete with folds at the ends.
