Do you have everything & the kitchen sink in your glove box, stuffing it so full that you have to slam it shut with spare napkins, plastic utensils, straws, ect. all which you'll never use. When the glove box hinge give out you can buy a new one which is out of stock in most places for ~$70 or depending on material & infill you can use this.

I did use PLA to print this, so far under the stress my sister puts on the glove box it has held up for a little over 2 weeks. I'll let you all know if PLA isn't strong enough. 

At 80% infill

I Glued then I plastic welded the seams 

I haven't filed down or rattle canned it yet.
