They seem to be pretty standard so it might fit your unit.
I added two small holes because I couldn't get far into the suction before the dyson stopped without them.
The manual pump is useful if you want to get that last bit of air out, but i found with clothes that the space saved is minimal and turns the clothes into a rock.
Prints without supports.
