Looks good and should work just fine!!!
Might want to make a few more if you're going to need feeders on a weekly basis.
One thing I do to keep a steady flow of feeders with my rats is to cycle the females through a males cage and remove them before they give birth. This method works very well on small scale programs as it avoids the feast/famine effect of too many/few litters born in a given week. Another benefit is by having a weekly cleaning/cycling day is the litters will be born pretty much the same day every week so you'll have appropriate size feeders they same time each week.
I've done cycle breeding with mice before but am now tub breeding them as I need lots and simply freeze off any excess. During baby season I need way more than I can produce and those frozen ones come in handy.
