This is a remixed version of the great card by Thingiverse user Nakozen (Creative Commons lic / no commercial use): https://www.thingiverse.com/thing:4689896
But I based this particular update on the Biggsandwedge user's remix, as it had relaxed tolerances (which I was finding I needed): https://www.thingiverse.com/thing:5166977
Updates:
Details now printable on the back of the house
Included a few custom detail bits for the back of house:
Added card kits with messages in various languages
I've also left everything pre-positioned in a Meshmixer .mix file
You can also create your own custom image / text detail for the back of house
Use same method (OpenScad and Meshmixer), to change the message along the frame (see sample photo where I added a custom Xmas message to my print)
Additional Credits:
With this model, one has the ability to customise the text, and the model has been set up so that with the use of Meshmixer (after learning some basic steps) it is easy to create a custom design (all the pieces are already in place in the model, and can be turned off/on, or new layers added). Using this approach it is customisable, by definition... but please note it cannot be wholly customised by use of just the customiser plugin (which only will pick up the text/image Scad file).
For multiple colours, need to add "Filament Change" script (if using 0.2mm layers, then it will need to be at layer 10). See https://all3dp.com/2/ender-3-change-filament-mid-print/
Don't worry too much about fine stringing when printing. A hot air gun breifly over the print at the end will tidy things up nicely.
