Feel free to try them out. The 24mm design has been working great, but needs more long term testing before they are out of beta.
The 24mm Max Feeders use exactly the same hardware as the 8mm kit which you can buy here: https://store.curlytalegames.com/pages/max-feeders
Follow the same instructions as the 8mm assembly and Open PnP configuration, however instead of feeding 4mm in Open PnP you'll want to feed 8mm.
