Dimensions, fit & print notes

BRAMBLE · Articulated forest dragon One curled dragon with leaf armour, fixed legs and horns. The main STL contains 11 retained bodies linked by ten print-in-place ball-and-socket joints. Legs, toes and the long tail do not articulate separately. Size: 164.171 × 167.278 × 41.997 mm at 100% in millimetres. Start with BRAMBLE_Coupon_0.45_mm.stl. Three coupons have nominal radial clearances 0.35 / 0.45 / 0.55 mm; the dragon uses 0.45 mm. Print the 0.45 mm coupon in the intended material and settings. Check elephant-foot compensation, movement and neck strength. Do not force a fused joint. If the coupon does not work, do not print the entire dragon. For single-colour printing, import BRAMBLE_PrintInPlace_Mono_mm.stl as one assembly at 100%. Keep the original curled pose. These retained joints cannot simply be snapped together from separately printed parts. Do not scale the model: scaling also changes the working clearances. Place the supplied flat underside on the bed. Do not fill joint interiors with supports. Inspect the air gap throughout every sliced joint. A 0.4 mm nozzle, 0.20 mm layer and three walls are starting points for inspection, not verified presets. Small connected overhangs under ears and feet and short bridges of about 3.8 mm at joint necks may affect print quality. Support-free printing is not guaranteed. External local supports, if needed, must not enter the joints. The print ZIP also contains BRAMBLE_4Colour_mm.3mf as an optional four-colour geometry assembly. It is not a printer profile or ready G-code. Keep all colour regions aligned as parts of one assembly. Assign materials and verify bed, extruders, temperatures, purge and supports in your slicer. Import compatibility and printer behaviour are untested. A standard single-extruder printer cannot reproduce all four regions merely by pausing at layer heights because colours share layers. Earlier digital checks covered the resting pose, 490 individual joint positions and a limited movement envelope; they do not establish collision-free movement in every combined pose. Physical friction, retention force, layer strength and wear remain untested. Not a certified children's toy; horns, toes and joints can break into small pieces. Digital geometry has been checked. No machine-specific slicing, physical printing, strength or practical fit test has been performed. Print time and filament usage are unknown. Inspect all sliced layers, supports and first-layer adhesion. Render images show the model, not a printed product. STL contains geometry only, without colour. Editable source files are not included.

Time and filament use, where available, are slicer estimates for a stated file and profile, not measured print results. Filament used is not the finished part’s mass. Missing values mean there is no verified slicing source.

Assembly & use instructions

Before printing

  1. One curled dragon with leaf armour, fixed legs and horns. The main STL contains 11 retained bodies linked by ten print-in-place ball-and-socket joints. Legs, toes and the long tail do not articulate separately. Size: 164.171 × 167.278 × 41.997 mm at 100% in millimetres.
  2. Start with BRAMBLE_Coupon_0.45_mm.stl. Three coupons have nominal radial clearances 0.35 / 0.45 / 0.55 mm; the dragon uses 0.45 mm. Print the 0.45 mm coupon in the intended material and settings. Check elephant-foot compensation, movement and neck strength. Do not force a fused joint. If the coupon does not work, do not print the entire dragon.
  3. For single-colour printing, import BRAMBLE_PrintInPlace_Mono_mm.stl as one assembly at 100%. Keep the original curled pose. These retained joints cannot simply be snapped together from separately printed parts. Do not scale the model: scaling also changes the working clearances. Place the supplied flat underside on the bed. Do not fill joint interiors with supports. Inspect the air gap throughout every sliced joint.
  4. A 0.4 mm nozzle, 0.20 mm layer and three walls are starting points for inspection, not verified presets. Small connected overhangs under ears and feet and short bridges of about 3.8 mm at joint necks may affect print quality. Support-free printing is not guaranteed. External local supports, if needed, must not enter the joints.
  5. The print ZIP also contains BRAMBLE_4Colour_mm.3mf as an optional four-colour geometry assembly. It is not a printer profile or ready G-code. Keep all colour regions aligned as parts of one assembly. Assign materials and verify bed, extruders, temperatures, purge and supports in your slicer. Import compatibility and printer behaviour are untested. A standard single-extruder printer cannot reproduce all four regions merely by pausing at layer heights because colours share layers.
  6. Earlier digital checks covered the resting pose, 490 individual joint positions and a limited movement envelope; they do not establish collision-free movement in every combined pose. Physical friction, retention force, layer strength and wear remain untested. Not a certified children's toy; horns, toes and joints can break into small pieces.
  7. Digital geometry has been checked. No machine-specific slicing, physical printing, strength or practical fit test has been performed. Print time and filament usage are unknown. Inspect all sliced layers, supports and first-layer adhesion. Render images show the model, not a printed product. STL contains geometry only, without colour. Editable source files are not included.

Public demo · digitally reviewed models

The original models have passed digital geometry and visual reviews. Each model states its own print status. Digital checks do not establish physical fit or load capacity. Studio profiles describe the editorial catalogue; registered user accounts are not available.
