Cant load 3d object using Ar.js for Geo Location

I’m learning htlm to create a AR experience, but i know very little about everything. I’m using Glitch to code and test.

I managed to code a basic location-based ar experience, but very simple with the primitive objects, like the a-box.

i am trying to put other things instead of a yellow box, so I’m using the same html, but adding the a-assets to import my model,

I cant find where i am getting it wrong, because it doesnt show up anywhere.
