Halloween Standing Bubble Letters A–Z — Printable Files (STL + 3MF)
$15.00
The whole bubble alphabet, A–Z, dressed up for Halloween, as STL and 3MF files. Every letter stands up on its own.
Spell BOO on the mantel, a name on the party table, or TRICK OR TREAT down the bookshelf. Each letter has its own raised Halloween icon all over the front: pumpkins, ghosts, bats, black cats, witch hats, moons and stars, and a spider web.
🎃 What makes these different
👻 They actually stand up. Every letter has a flat bottom it sits on. No hooks, no nails, no stand.
🦇 Icons built into the letter. The icons are part of the letter itself, raised in the same colour, so it prints in one filament with no colour swaps and no AMS needed.
🖨️ Made to print standing up. Standing up, every pumpkin, ghost and bat builds up crisp, and you don't get layer rings across the puffy front. Bubble letters often get sanded smooth afterwards, but sanding would take these icons right off. So these are designed to look good straight off the printer.
📏 Every letter is exactly the same height. All 26 stand exactly 150 mm (5.9 in) tall, so any word you spell lines up on the shelf.
⚠️ Please read: these need supports
Because they print standing up, crossbars and arches need supports. The files don't turn supports on for you. Slicers only trust settings saved for your exact printer, so you switch them on in a few clicks: tree supports, on build plate only, plus a 5 mm brim. The Start Here PDF walks you through it step by step for Bambu Studio, with notes for OrcaSlicer, PrusaSlicer and Cura.
💸 Save time and filament
They're shelf decorations, so they don't need much inside. The PDF shows you how to switch to 10% lightning infill (the fastest, least-filament option, and what I print with), or 10–15% gyroid if little hands will be playing with them. It also includes the exact settings I printed my test letter with.

Size and print details
- Each letter stands 150 mm (5.9 in) tall and is about 4.5–6 cm (1.8–2.3 in) deep.
- Widths range from 108 mm for the I to 200 mm for the W.
- Want them bigger or smaller? Scale them in your slicer. Use the same percentage on every letter so they stay matched (the PDF has a size chart).
- At full size they need a 256 × 256 mm bed (Bambu P2S, P1S, X1, A1 and similar).
- On an A1 mini or another 180 mm printer, 24 of the 26 fit as they are. Scale M and W to 84% or smaller, or the whole word to 84% (about 126 mm tall), to keep it matched.
- One colour per letter · supports needed (tree, build plate only) · no glue · no assembly.

FAQ
Do I need a Bambu printer?
No. The STL prints on any FDM printer, and the 3MF opens in Bambu Studio, OrcaSlicer, PrusaSlicer and most other slicers.
Why do I have to turn supports on myself?
Slicers ignore print settings that weren't saved for your exact printer and filament. Turning on tree supports takes three clicks, and the PDF shows you where.
Can I print them lying down instead?
You can, but the icons come out blurry and stair-stepped on the curved front. Standing up is what keeps them crisp.
Can I choose which icon goes on which letter?
No. Each letter comes with its own icon, arranged so neighbouring letters in a word don't match. The full list is in the PDF.
Do I need more than one colour?
No. Each letter prints in one colour. The icons are raised in the same filament. Mix colours across the letters for that orange-black-purple look.
Can I sand or coat them?
Sanding would take the icons off, so they're designed to look finished straight off the printer.
Can I sell what I print?
Not with this download. It's a personal use license. To sell prints you need a commercial license, so email support@3dprintedmom.com and ask.
Can I share or sell the files?
No, never. Not with friends, not in a group, not on any site, and not free. Only 3D Printed Mom sells these files.
Is this a physical product?
No, it's a digital download. You get the files, and nothing ships.
