One of the things about 3D printing that doesn't get talked about enough is how well it suits seasonal home decorating. Not big statement pieces — it's not replacing furniture — but the small stuff that changes the feel of a room across the year. The things you put on a windowsill or a mantelpiece or a hall table that say, without saying it, that a particular time of year has arrived.
We started printing seasonal items almost by accident. Anna wanted tulips for spring and I thought: we have a printer, we could just make some. A few hours and a roll of pink and green filament later, there were tulips on the windowsill that didn't need watering and wouldn't die after a week. That was the beginning of what's now become a year-round habit.
Spring — tulips
The tulip collection has gone through several iterations. The first version was simple — a basic petal shape, a stem, printed in two colours. It worked but it looked printed. The current version has a layered petal structure that gives the flower a much more realistic profile when you look at it from the side. Getting the curve of the petals right took some experimentation with the slicer settings.
We print the stems in green and the petals in whatever colour suits the room. We've done soft pink, deep purple, a warm yellow. The multi-colour capability on the Kobra 3 means you can get a proper gradient from green to petal colour without any seams or manual filament swaps.
A vase full of printed tulips takes an afternoon of printing time and costs very little in materials. They look good on a windowsill in natural light, and unlike real tulips they're still there in week three.
Autumn and Halloween — pumpkins
Pumpkins were the second seasonal project and they've become some of our most printed items. We've made them at several scales — small ones for scatter decoration across a mantlepiece, a medium version for a shelf, and a large centrepiece that came off the Tronxy XYC 400 in a single print because we needed something with presence for the hall table.
Orange pumpkins are the obvious choice but we've also printed black ones, a deep burgundy that looks unexpectedly good, and a two-tone orange and black version using the multi-colour setup. The stems are a separate print in dark brown or black and press-fit into the top.
The satisfying thing about printing pumpkins is the cost. A medium-sized pumpkin might use 80 grams of filament. At current PLA prices that's well under a pound in materials. Buying ceramic or resin pumpkin decorations of equivalent quality from a shop would cost considerably more and you'd have no control over the size or colour.
Christmas
Christmas has been the most prolific season for printing. The list of what we've made over the past few years includes: small tree ornaments in various shapes, a star for the top of the tree, a set of snowflakes in different sizes, a few candle holder designs, small gift boxes for placing on tables, and a collection of miniature houses that look good grouped together.
The ornaments print quickly on the Kobra 3 — a small bauble-style decoration might take twenty minutes. That speed means you can iterate on a design, try it, adjust it, and run another version the same evening. We've refined several designs over multiple years, improving details each time.
Silk filaments look particularly good for Christmas items. A silk gold or silk silver gives decorations a sheen that catches light in a way that flat PLA doesn't. For items that will hang near lights or candles, it makes a real difference.
Easter
Easter is newer to the seasonal printing rotation. We've printed a set of egg designs in various sizes — small ones for an egg cup display, larger hollow ones — and a couple of rabbit designs that Anna found online. One of them, a sitting rabbit with a simplified but effective silhouette, has become a fixture on the hall console table every year.
Easter lends itself to pastel colours, and there are some excellent pastel PLA options available. A soft mint green, a pale lavender, a warm off-white. Printed at standard settings these look appropriately seasonal without being garish.
Why this works well
Seasonal decorating with a 3D printer works because the constraints match the use case. You want items that are the right size, the right colour, that can be replaced or updated, that don't need to last forever. 3D printing gives you complete control over all of those things.
If a decoration breaks — a pumpkin stem snaps, a tulip petal cracks — you print another one. If you want to try a slightly different size next year, you scale the model. If you find a better design, you retire the old one and print the new one. You're not committed to objects in the way you are with bought decorations that you then feel obligated to use because you paid for them.
The cost per item is low enough that experimenting feels fine. Some prints work better than others. The ones that don't get recycled. The ones that do become part of the seasonal rotation and come back out year after year.
