Heart - Impossible Passthrough

Hi,

for some time now I wanted to play around with these cool passthrough designs but I didn't know how it was done. I found a good video about it (here) some days ago and tried it out. This passthrough heart it the result.

Filament used:
Overture Silk Copper PLA & FormFutura PearlGold Easyfil ePLA

my print settings:
- 0,4 nozzle @ 0,25 mm layer height
- 2 walls
- 5 % gyroid infill 
- supports: yes, on build plate only
- print orientation: as in pictures
- place seams on sharpest corner or "alinged" in prusaslicer 
- XY Size Compensation: -0,2 mm
- print time: 2h41min & 2h56min on prusa MK4 with a custom stealth profile at around 100mm/s

notes:
- after importing the *.STL into the slicer >> split model to objects to get both parts
- with importing the 3mf file the slicer software should ask if you want to split the model
- the parts are designed without any tolerances in Fusion (like in the tutorial video), so before printing you have to add a clearance of -0,2 in the slicer software (Prusaslicer - Print Settings - Advanced - XY Size Compensation), I applied the clearance once within the 3mf print file and then printed both parts seperate out of the same file
- clean both parts thoroughly after print from blubs, little bumps and stringing to make the parts pass through smoothly

Happy printing!
