Hard to get last pieces of tissue paper? Never happen againTissue papers Always On Top now!A plate and a set of spings is added to the tissue box, so tissue papers will come up close to the lid, instead of droping back to the box and hard to get.I am by no means the first to have this idea, but I didn't see anyone who uploaded any 3D printed sping tissue box designs, so I do it.Features:Fully 3D printed, no other components neededOnly sping components need supportsPETG@@0.2mm layer height 15% infill tested, available to use itAbout springs:If you seek PERFECT PRACTICALITY, metal springs are perfect choices obviously.
