"T Fuel" Drink Powder TPU Travel Plug

I needed a TPU travel plug for my drink powder scooper, so I made it! I also have a model for the scooper, see here!

What is “T Fuel” though? Nothing really, just thought it sounded like a cool name for a drink powder. Someone should make that a real thing! T stands for “Timmy,” of course.

Print settings:

• I have only tested my plug on the X1C with a 0.4mm nozzle, using Polymaker PolyFlex TPU95.
• If you try it out, let me know how it goes!
• You will need to dry out your filament and store it correctly for optimal printing. I have set the profile up to work for my prep work and setup, but please see resources online for your chosen filament type, and adjust your print/filament settings as needed!

How to use:

• The travel plug goes in with the handle opposite the scooper handle, and with the leash tied to the slot in the scooper handle. See instructions below, and/or pictures.

How to assemble the plug to a scooper:

Note: Pictures shown using 1 hand, but it's easier using 2 hands. It's meant to be slightly difficult to assemble, so that it's not easy for it to come undone on its own. It's really not that bad though :)

1. Pass the end of the leash upward through the scooper slot.

2. Align the nub on the end with the ring.

3. Start to push the nub through the ring. I've found this is easiest by pushing down the long end of the leash where it meets the ring, as shown.

4. Push down on the ring with 2 thumbs (1 illustrated below, lol) so that the nub pokes all the way through.

5. Celebrate!

How to disassemble the plug from the scooper:

1. Using the side of one thumb, push up on the handle. It should pop out with a nice sound, easily!

2. Do NOT pull on the leash, this could lead to tearing over time. Instead, push the ring around the nub. 2 thumbs may work best.

DISCLAIMER:

This item is designed to be used exclusively with a dry powder/item and not to directly interact with the mouth or anything wet, so it should be safe to use. However, the following must be stated regardless.

It is not known if printed filament is officially (generally) food-safe. Typically, filament on a spool is safe on its own, but once it's printed, it may be contaminated from traveling through a PTFE tube, extruder system, the nozzle, and more. Additionally, imperfections and gaps between print layers can potentially house dangerous bacteria, etc., and not be cleanable once used. If any models I provide are printed and used for food/eating/drinking, I advise that they be thoroughly washed and dried after printing/before using, and ultimately be considered a 1-time use item. I and Bambu/MakerWorld do not assume any liability for the use of this item for any situation. Use your brain.
