so i found this on yeggi ages ago. printed it and loved it but it was just a front and back. so i used my massive skills and over ther coarse of many months i figured out how to split the buttons out and the antenna and screen. if you want to add springs behind the buttons just sink them into the print space a few mm. also may want to try printing them at 95% scale if your first attempt is too tight.
finally i suck at modelling this was a joke i hope you get some use out of the little bit ive done
the original is on yeggi somewhere sorry for not knowing how to add its source
