It can be adapted to any size, and u can also make it stronger.
See u in step 1!
Step 1: Building the Frame
The first pic is my frame shape. U can build ur frame any shape u want, but dont make it too tall, or it miaght fall over, unless u make it wider. also, the bigger u make it, the more pieces it will take.
Once u have ur frame shape, u have to determine how strong to make ur shelf. It will be one grey rod from front to back. i built the frame 8 times for the amout of strength i need. But, if ur going to put something heavy, like books, on the shelf, u may want to build more layers. u could build enough layers to fit the entire grey rod. This would make it completely solid.
However many layers u do build, u will need to put spacers in between each layer unless its solid. With 8 layers, u need 2 greys in between all layers except the last one, and one blue on the end.
Step 2: Finishing
on the bottom 2 corners, front and back, attach a yellow connector with a white rod on it to the grey rods instead of a grey endpiece. This adds stability. See pic 2! If u built it tall and skinny, add some long rods onto the yellow pieces, going outwards.
All done! post mods, questions, and pictures of ur completed model to give others ideas!
