The SCAD file has some parameters at the top that you can manipulate to match your can. The connection module can also be tweaked if you want to try a different shape (it will automatically be mirrored in the positive and negative. Change the parameters to match your cans and then print out as many as you need. Glue/Tape the tabs together and you've got a stacking system!

// platform height
p_h = 1.5;
// can height - between ridges
can_h = 106.5;
// can diameter
can_d = 73;
// bump height
b_h = 15;
// connection length
c_l = 4;
// center_cut percent
c_c = 0.4;
//connection circle
con_d = 10;
//minokowski
min = 5;

// how fine the circles should be, higher is better, lower is faster to render
