Easy penholder A1 / A1 Mini Plotter

Many have asked for a simpler version of the A1 plotter attachment I made a while ago.. here it is. No bearings, no linear rails, no spring, no ziptie and fewer printed parts. To solve the linear flex motion the rails and spring provided in the original version I've integrated a printed spring into one of the parts.

This version consists only of 3 printed parts. The base is unchanged and remains as before such so that the ones who have printed it before can reuse it. The penholder remains the same but is mounted differently. The spring is know a compliant mechanism instead - not as stiff as the other version but it will work well for making some drawings.

Assembly is quite straight forward but I recommend that you use the guide in from the old model if you have questions:
