Test Tube Feeders — 3D Printed, 3 Pack

Shipping: UPS/FedEx 2-Day, $20 flat — free on orders over $120.

Feed the tube without flooding the tube. Our custom 3D-printed feeders slot into a standard test tube setup and end the messiest part of early colony care: getting food in without drops soaking the cotton or workers drowning in nectar.

Details

• Grooved nectar channels — sized so workers drink safely; no open droplets, no drownings.
• Protein platform — a dedicated spot for feeder insects, easy to place and easy to pull before leftovers spoil.
• Two sizes: 16mm and 18mm, matched to your tube's outer diameter — same sizing as our PVA sponges and test tubes.
• Pack: 3 feeders.
• Rinses clean and reuses; printed in-house by Royal Chamber Ants.

Feed in the feeder, pull what's uneaten in a day or two, and keep the chamber itself spotless — that's the whole trick to a clean founding.

From their chamber to your door.
