A remix of a remix from Haprog, an extension is added to the model, intended for the Mini's tube to be slid in and with a thin zip tie or some adhesive tape hold it in place.
Some support is needed for the extension. Also PETG is recommended i guess, for the extension to have some give.
Only thing you need to provide is the thin zip tie and 2 small pieces of sponge, to be placed in the two sides.
