connecting toy brick

this is my first model took me 2 hours to design i hope that you all like it and download/print it because I am trying to make enough money through 3d models to buy a Bambu labs p2s combo if you would download and print this it would mean much to me, I have already did a test print of a few to make sure that they work and they connect fine. i am looking forward to making so many more fun projects. if you have any feed back just leave it in the comments please :)
