Christmas Gift Envelope

A remix of my own blank envelope template to make it Christmas-themed - with the “Merry Christmas” text and Christmas tree added to the front, and ol' Santa squeezing down a chimney on the back. 

Requires a printer with multicolour capability for full effect - MMU3, AMS or multiple toolheads. Although, since the text and graphics stick out, you'll still be able to make them out even if printed in a single colour.

Has folded dimensions of 165 x 80 mm and doesn't require glue.

The colours are (mostly) on different layers so prints relatively quickly. Kinda like HueForge, except I modelled and set the heights of the objects manually. Since the height for each colour is only around 0.32 mm thick, it'll print best in filaments which are less see-through. So PLA Silk and PLA Matte will look a lot better than regular PLA, although I haven't tried printing with the latter.

Folding the template:

1. Have the inside of the envelope facing you
2. Fold the two sides inwards along the fold lines 
3. Fold the bottom inwards along the fold line
4. Insert the two tabs on the bottom into the sides
5. Fold the top along the fold line
6. Insert Santa's legs and the flap on the top into the slot at the top of the chimney to close.

Print Settings

There's a 3MF each for Prusa Slicer and Bambu Studio. Use one of those files, otherwise, these are the print settings used: 

Global:

• 0.15 or 0.16mm layer height, 2 walls, 15% infill
• Arachne wall generation
• The fill direction angle should be 45 degrees to the folds. (In the Prusa Slicer version, since the model is rotated 45 degrees, it's 0 degrees.)

Height range modifier to add the colours to the the layers:

• 0 - 0.64mm : Red
• 0.64 - 0.80mm : Yellow
• 0.80 - 1.12mm : White
• 1.12 - 1.60mm : Green
• 1.60 - end: Yellow

In addition the model is separated into parts, with the top of the tree and the base envelope apart from the middle section have their filament changed to green.

The middle top of the envelope also has 0 wall loops and Octagram Spiral top surface pattern.
