On several of the components the Red and Black are reversed. Like on the multimeter. On the powersupply however the Red is to the left and Black is to the right.
When the colours are mixed like this the sketches get unneccesary complicated. A link to an example: https://www.tinkercad.com/things/lakP4ruBruM
Maybe a settings to revers the terminals can be added or in this case simply fix the element.
