Figured I'd make another Infinity Heart design, but this time one that would allow for adding names to each side of the infinity sign [on those lines]. For the names the easiest thing to do would be to going to tinkercad.com, use their text object to create names as a model and export them as stl's, print those separately and just glue/rest them on the bars in this design. You could even add a date to the bar across the bottom of the heart.

Dimensions

I made the profiles to fit the print bed of the A1 Mini so all printers could print it so given that profile the dimensions are, Heart end to end is about 130.5mm, Height is 85.5mm. Theres about 43mm of length on the lines for names and 30mm for date, but if you have any printers with the bigger print bed I'd scale it up to give yourself even more room for names/dates. Keep the Z height the same though or you'll have to adjust the layers in which the colors swap.

The second profile is the design without the bars or “&” in the middle. They are both print by layer for the color change of the heart vs infinity logo, but you can always use the same color to print as one color.
