Step 1: Desing

I made the Pipe with Tinkercad.

Just attach a tube on a larger tube and make a hole inside. Id you are interested in 3D design this is a must for you to test out.

*EDIT*

Taller version of the pipe uploaded.

Step 2: Pipe Is Done

The pipe is printed with Pritrbot Simple Maker's kit.

This is a full PLA print. No support or anything. Flip the print that way the larger part is down. The bottom part is thick enough not to need any support in printing.

Print settings.:

0.4 mm nozzle

0.2 mm layer height

60 mm/s print speed

15% fill in hollow part

Print time was about 2 hours.

Step 3: !!Warning!!

Before you start to dig out the flytrap make sure you don't touch these spikes inside the plant's leaves aka"mouth".

If two of these spikes is touched at the same time the "mouth" will close.

It is not venomous or anything it's just that the flytrap has limited quantity of reopening's on the "mouth".

It may be fun to try out with finger. Use a fly or Super Mario instead if you must test it out.

The mouth can re-open about 7 time's on its lifetime per leave. More leave's will grow out if the plant is healthy.

If there is a insect inside the mouth it can take for few days to even moths to reopen again. This depends on how big the insect was and how long it takes to digest it fully.
