My wife wanted some sewing weights to help her cut out her fabric pieces. I modeled these with washers I had laying around. They are Flat Washers, and the size for the small is 3/8 and the large is 1/2.
The tray while not necessary, looks cool, at least in my opinion.
I printed all pieces with a .3 layer height and 15% cubic infill.
The author marked this model as their own original creation.
