This model is designed to solve an issue with making a mess when trying to refill the reservoirs on an Origo alcohol stove. The funnel is designed to almost fill the mesh fill area on the reservoirs, while leaving enough space to see when the reservoir nearly full.
The files are to print as a vase with no base. Printed with the narrow opening downwards as shown in the pictures.
Tested on MK3S+ and with Prusa PETG.
thanks to Philipp for the Mason Jar original on which this is based!

Thanks to Philipp for the original model. To make his Mason Jar funnel work for the Origo stove, I increased the X and Y dimensions by 130% in order to size for the fill area of the alcohol reservoir without making the funnel any taller.
