this is for version 1.21 of rftoy from https://rftoy.rayshobby.net

case fits the nrf modules as well as the 433 and 315 mhz rx and tx modules

protects screen (unless your rftoy is significantly taller than mine... be careful!)

holes that lead to the buttons are intended for 1.25mm fillament. I captured mine with some electrical tape. works OK.

has places for screws/hotglue but also does a pretty good job of staying together with no hardware at all.

what it does not do is provide access to the switch that lets you select power from battery or usb. heh... oops. add that yourself :p
