A matching set of six printable Halloween pieces that are actually useful on a desk: a ghost lantern for an LED tealight, a coffin box with a snap-fit or magnetic lid, a jack-o'-lantern pen holder, a ribbed pumpkin bowl with a stem lid, a bat trinket tray and a ghost phone stand with a charging slot. Every part prints without supports.

What's included (12 parts, STL + 3MF, plus 5 ready plates)

• Ghost LED lantern (97.0 x 77.5 x 98.0 mm): 1.8 mm glowing shell with a round head, raised arms, scalloped hem and cut-out face, and a base that holds a standard 38 mm LED tealight
• Coffin storage box (76 x 156 x 45.5 mm with lid): bevelled outline, side panels, two lid versions (snap-fit or 6 x 3 mm magnets) and an optional cross inlay for a second colour
• Jack-o'-lantern pen holder (84.9 x 87.0 x 103.8 mm): soft ribs, rounded rim, carved face, 6 mm weighted floor
• Ribbed pumpkin bowl (133.6 x 133.6 x 61.5 mm) with a stem lid that locates on the ribbed rim
• Bat trinket tray (169.8 x 54.6 x 15.0 mm): rounded rim, coved floor, engraved happy eyes
• Ghost phone stand (112.7 x 106.0 x 136.9 mm): 67 degree rest for 6.1 to 6.9 inch phones in a case (up to 14 mm thick), cable slot and tunnel for USB-C or Lightning, recesses for rubber feet

Print settings

• PLA or PETG, 0.4 mm nozzle, 0.2 mm layers, 3 walls, 15 to 25 % infill, no supports
• Ghost shell: 4 walls (solid 1.8 mm), white or natural PLA for the glow, 5 mm brim
• Print as supplied: every file is already in its print orientation
• Every part fits a 180 x 180 mm bed; the plate 3MFs are laid out for 256 x 256 mm

You'll also need

• One 38 mm LED tealight (battery type, never a real flame)
• Optional: 8 neodymium magnets 6 x 3 mm (magnetic coffin), 4 rubber bumpers 10 mm (phone stand)

Includes the editable .blend and the Blender Python scripts that generate every part, and an audit file per part.

Blender check (Blender 5.2.1, automated)

• Every part: no self-intersections, no degenerate faces, flat first layer, walls 1.2 mm or more (ray-cast; the only thinner readings, under 0.1 % of any part's surface, are knife edges where openings are cut through curved walls and the edges of the bumper recesses).
• Overhang above is short bridging only (largest span 11 mm): face and hem openings, the cross recess and groove ceilings on the bed side of the lids, the bumper recesses under the stand. No supports needed.
