My children find joy in the simple act of screwing and unscrewing objects, but assembling bolts and nuts can sometimes lead to frustration. To tackle this challenge, I created a closed bolt design, which has become their absolute favorite. Although originally intended for young kids (age 18+ months), this model surprisingly captivates adults as well.
For an optimal printing experience, it is recommended to use minimal layer heights. Initially, I utilized a layer height of 0.12mm, which yielded satisfactory results and takes 1h less print time. However, upon further experimentation, I found that a layer height of 0.08mm provided superior outcomes, ultimately leading to the best overall quality.
During the initial one or two rounds of screwing, you’ll encounter a gentle resistance. However, fear not! This minor friction will swiftly dissipate, resulting in a remarkably satisfying experience.
