Gridfinity 4x7 desk drawer

So, in need to organize my desk, I designed a drawer system that can sit on its own on the desk or to fit it in a 4x7 gridfinity base plate. You will find a 8x7 base plate in my designs that I made it for my drawers. Inside, you will see that there are 4 insertion channels. I designed it this way, in order for you to slide and glue a string of TPU. This way, when you slide the drawer, it will smooth out the sliding sound - but its mandatory to glue the strings - note it takes more time than PLA to glue it. The drawer will work even without the TPU strings, but it will be a bit more loose. The handles have to be glued also.
