Turn your leftover 1.75 mm PLA filament into the ultimate cat toy! Use this mold to make a spring your cat will love.
This model was designed based on the idea of the device for PLA springs, with a few modifications:
- The mold is made for use with 1.75 mm filament.
- The produced spring has 4.5 turns.
- The attachment ring at the bottom of the mold enables use without the need for tape.
- The top surface has the required filament dimensions embossed.
To create a spring:
- Cut a 30 cm long piece of PLA filament.
- Soften the filament in 80°C (175°F) water for 3-5 min.
- Insert a tip of the filament into the small opening at the top of the mold.
- Press the filament into the grove from top to bottom of the mold.
- Insert the second end of the filament into the small ring at the bottom of the mold. (Optional) Trim off the spare filament.
- Put the mold with the filament on it into 80°C (175°F) water for 3-5 min.
- Put the mold with the filament on it into room temperature water until cooled or run under the tap.
- Remove the spring from the mold.
- (Optional) Trim off the parts of the filament that were inserted into the opening at the top of the mold.
