About this model

Frustrated at no free or paid models already being online, but PLENTY of ebay listings for already printed ones, I decided to try and make my own from the ground up. Not perfect, but pretty alright. I used these battery contacts: I recommend hot glue for holding the connectors in place, but in a pinch, as long as your settings are perfect, you can use friction fitting for the contacts. Putting a piece of tape to make a little "handle" in the middle helps with getting the battery out. Originally I modeled a slot to put a ribbon or tape, but it ended up just making the model weaker overall. If this saves on of y'all, the model was a success 🫡 I no longer have my DAT Walkman, so I will not be making modifications as I have no way to test fitting.
