Well, I first tried duct tape - that worked for a while. Then I bought laser, 5 minute fix glue - that didn't work at all. Finally, I ordered the crisper drawer from Appliance Parts. I received it the day after I ordered it, the drawer fit, and I am happy.
Regarding the question "How challenging was it to repair the appliance yourself", it was only easy after I ordered the drawer from Appliance Repair. Prior to that, it was pretty frustrating.
