You can own your very own T88!
Print this as a hollow prop, with the door held closed with 8x 3mmx3mm magnets. or, if you'd like to make it functional, all you need is:
1x 9v battery1x 9v battery connector1x momentary switch - I went with this one: https://www.jaycar.co.nz/small-black-spst-n-o-momentary-action/p/SP07003x 3mm blue LED's (+ resistors)1x 3mm green LED (+resistors)
This is my first time making a functional prop, so its not perfect, but its better than the other T88's I've seen out here.
Enjoy!
