Ant test tube retractable feeder(16mm)V2

thingiverse

I tried to find a way of feeding ants without having to remove the cotton every time from the test tube. Here's my solution. 1. Push both the feeder and the blocker to maximum in the feeder support 2. Insert the assembly in the tube with a piece of cotton to avoid escapes 3. Remove the feeder part and put whatever you want in it. 4. Slide the feeder back to max. 5. Retract the blocker to reveal the meal and voilà ! Print the blocker and the feeder laying flat on bed with supports for the feeder cup. And print the insert standing up like the picture in blue. I used a raft of ten turns for each parts 2020-09-12 UPDATE: ADDED A SHORTER VERSION
