CrumbleHopper
thingiverse
Designed this to simplify the tracking of mouse food intake. It hooks onto the grill in a Tecniplast cage, and can be easily inserted or removed for weighing of food. We have used this with mice, and they will happily eat from it; even crumbly food will stay in and they weren't able to kick bedding into the food hopper, as we have seen with other devices.
