SONY MD Walkman MZ-R90/91 Battery Door (Part# 4-223-077)
thingiverse
Ages ago, my MD walkman battery door broke. I could barely get my player to work so I retired it for the time being. I finally got motivated to fix it and decided to create a replacement door since they are very hard (and expensive) to come by. Is it perfect? Absolutely not! But it is better than having half a door :) Feel free to modify, improve, etc. I'd love to see people with more skills take a swing.
