Weekly Challenge Group

Created by Arin Swadi on 30 August, 2021

I challenge you to find a solution for the following problem:


A sheet (dont care about material or strength) need to be bended. There is an existing bending line in the sheet, so the material will bend on this line automatically.

Use the following stepper motor as power source.

The construction need to be fixed on Aluminum profiles 40x40mm. (Like ITEM profiles etc.)

If possible don´t use solutions with pneumatic or hydraulic components.
