automatic dispenser

Açıklama

In the spirit of my first toilet paper dispenser design, I modified the system so that the elastic band is invisible and the recall of the movable legs is better. I have provided in addition 2 models , one for rolls of about 12 cm in diameter max, another for rolls up to about 14 cm in diameter. I have also provided a test to allow you to adjust your printer and check the operation of the joint (45 minutes to print and 3 m of thread about) I use a rubber strap of 3.4 cm in diameter put in double for the recall. The complete piece prints in 4 to 5 hours depending on model 'setting and printer and 18 to 20 m of filament.about Update,10/03/2020 addition of a version with hidden screws, make sure to insert the scroller a little force on the screws so that it does not come off when removing the roll, screw the wall screws with a center distance of 140.2 mm leaving little play.
