How I made it:

To create this 3D print, I started off by downloading the 3d print model by PLP on cults3d. I opened the robot file up in Cura and added the heart to the same board. I set my printing settings:

0.2mm resolution

10% infill -zig zag

200/60 temp for PLA

50mm/sec speed

Supports at 60° overhang angle -triangles 15% density

5-line skirt


Under 20-minute print, under 1" tall.

After that print, I sized the design up 300%, I used the same settings and had about a 3-hour print, about 2 1/2" tall.

The print turned out beautifully, I love both the tiny and the large robot! This is perfect for Valentine's Day.
