udated version of the a1 mini side box. allows storage of two a1 hotends and two packs of nozzle cleaning needles. the hotends can be fixed magnetically by inserting am metal piece (dimension 2x2x30mm, for example a nail….) like shown on the pictures. therefor u have to stop the print at layer 19 (0.4 nozzle) or layer 13 (0.6 nozzle) with a m400 command. have fun !
