I found the fantastic Laser cut tree in a round frame by mistercrunch and wanted to make a 3D printed version as a Christmas gift. Using the original file, a lot of small branches didn't print properly or fell off when removing from the print bed - the bottom curls were absolutely impossible for me to print well.
So I set out to make a 3D print-friendly version of the tree. This essentially meant manually redrawing every single branch and twig thicker and changing a number of details to be printable. I also spent a lot of time to make every curve smoother and feel more organic.
Diameter is 230mm and thickness 5mm; the latter can probably be cut in half if you plan to hang it on a wall, just remember that the trunk will have to support the entire tree.
Printed with 20% honecomb infill and triple walls, the entire print weighs 80g. Since there are no Z-details, 0.20mm layer height went fine.
The photos you see are after a 20-second cleanup (quick pass with heat gun to remove the finest hair-like strands), but nothing more is done so far.
Option 1: Hang it on a nail on the wall. For an absolutely flat finish, have the bottom side facing outwards.
Option 2: Hang it from a piece of thread in a window - the light shining through gives a lovely effect.
