Description
The ab roller is an effective way to train your abdominal muscles
***Use with caution***
I weigh ~70 kg, this was no problem. Work your way up slowly when using it.
Take the Prusa roll apart, insert the roller insert, and reassemble the roll. The roller insert is used to keep the roll stable.
The two handles can be screwed together using the thread. The thread offers some resistance when screwed together. This is intended and prevents accidental unscrewing during an exercise.
It is important to print the handles horizontaly; this increases stability significantly.
...you can just use it to have fun as a human wheelbarrow and race through the city
