Toolcart with printed joint connectors

The goal of this project was to see how much I could simplify the construction of something like this by leveraging modular connectors (the joints). You could assemble this using only a screwdriver and a drill (for pilot holes). You could have all of the wood cut for you (I intentionally had this done at home depot for some of the wood), and the connectors make up for any sloppy cuts. I did cheat a few times by gluing the drawer and mitering the angled pieces.

Connectors fit 1x2 wood. To assemble lower frame, you need:
2x bottom_a_with_wheel_hole
2x bottom_a_with_wheel_hole.flipped
2x bottom_a
2x bottom_a.flipped

To assemble upper frame:
1x bottom_a
1x bottom_a.flipped
1x bottom_b_angle_with_wheel_hole
1x bottom_b_angle_with_wheel_hole.flipped
1x top_b_angle
1x top_b_angle.flipped

Sets of 2x slidebracket, 2x slidebracket.flipped can be used to attach slides to bottom frame.

Sets of 1x anglebracket, 1x anglebracket.flipped can be used to attach platforms to top frame.

You can make the wood any length you'd like, but the dimensions I used are:

Lower frame:
8x 18" for horizontal pieces
4x 24" for vertical pieces

Upper frame:
4x 18"
2x 22"
2x 27.5" (These pieces need to be cut at an angle. It's a 3-4-5 triangle so the angles are: 53.13 and 36.87 degrees)
