No-Tie Shoe Laces (Secure Hold!)

So, this isn't exactly some super innovative concept BUT if you are one of those people who aren't exactly fans of tying shoelaces, have a 3D printer (or access to one), and have some TPU filament...This thing is for you!

My major focus while designing these was to make sure that once inserted, the laces remained securely in place. I found that other designs slipped out too easily. With these laces, the ends are slightly thicker, and have "hooks" for a sturdier hold. Personally, the one time I did try to remove one, I ended up having to cut off the ends because I couldn't slip them out through the eye-holes.

I have uploaded STL files with the following lengths:

• 40mm
• 45mm
• 50mm
• 55mm
• 60mm
• 65mm
• 70mm

To figure out what size you need, put on a shoe and measure the distance from one eye-hole to the opposite eye-hole. If you notice that not all the eye-holes are roughly the same distance apart, you might need to mix-and-match multiple sizes. For reference, I wear a US men's 9 and I used 45mm laces for all eye-hole pairs.
