Vacuum cleaner bag inlet for Singer 4527 ECO

thingiverse

My vacuum cleaner was not making a proper seal against the bag so the dust would go past the bag and clog the filter. This part is inserted into the inlet as a slight press-fit and sticks into the vacuum cleaner bag so that the dust must go in there. My vacuum cleaner bags have a rubber seal so this works well as the bag opening stretches around the printed part and makes a proper seal. De-burr the printed part and the vacuum cleaner before insertion to make it easier. Print with the part that goes into the vacuum cleaner bag on the print plate so that the top part which inserts into the vacuum cleaner doens't experience elephants foot.
