The file 'Dirt Cheap 28byj-48 Cat Door Opener (Fusion 360 Files Included) 3D Printer Model' is (f3d,stl) file type, size is 1.4MB.
Changes are you have something you want to automate.
Opening a miniature garage door, flipping a switch, locking a door etc.. but you don't want to spend a fortune doing that.
Well i designed something simple that use a minimum amount of plastic with the cheapest servo motor in existence and you can use it too.
The tolerance of the project is relative loose so you don't need a super calibrated printed to have something functional. 0.24 layer, 0.4 nozzle with pla prints well.
Give it a try and post your creation.
I included the Fusion 360 file so you can remix it easily.
Have Fun!
