3D Solutech and eSun Adapter for Robo3d Top Mount filament holder.

thingiverse

I designed an adapter for 3D Solutech and eSun filament rolls to fit smoothly on the top mount filament holder of Robo3D printers. The significant diameter difference between the two causes the rolls to wobble, leading to jams. This adapter resolves that problem. You will need to print two copies of this design, one for each half. Depending on your print quality, you may need to sand down the inside hole slightly. Both halves have an inner diameter of approximately 20mm, so ensure that your filament holder is close to this size. Filament holders smaller than 20mm are acceptable, but those larger than 20mm will not work. The eSun roll has a diameter of 51mm and the 3D Solutech roll measures 57mm. I also created a 54mm design for another brand of filament upon request.
