Belt Estimate Sketch

thingiverse

I was blown away by this design concept on paper, so I decided to take the plunge and start purchasing components. My goal is to upgrade my Ender 3 model and eventually modify it to increase its dimensions. To get an accurate estimate of the closed-loop belt length, I quickly created a sketch in Fusion and exported it as an F3D file. All you need to do is adjust the center-to-center dimension on the driven gears, relocate the drive mount assembly if needed, and then run an inspection on the resulting closed loop to obtain the estimated belt length. I'm open to feedback, but my initial thought was to add approximately 10mm to the calculated length recommended by the software.
