Flexi Trex

Flexi Mini T-Rex – Print-in-Place | No Supports

Meet your new pocket-sized prehistoric companion! This Flexi Mini T-Rex is a fully articulated, print-in-place model designed to come off the build plate ready to move—no assembly required.

Engineered with clean tolerances and smooth joint spacing, this design prints reliably on most FDM printers while delivering satisfying flexibility throughout the body and tail. Its low-profile, flat design makes it especially stable during printing and ideal for consistent results.

Perfect as a fidget toy, desk companion, or quick test print.

Recommended Print Settings (Profile)

Printer Type: FDM
Nozzle: 0.4 mm

• Layer Height: 0.16–0.2 mm
• Infill: 10–15% (Gyroid or Grid)
• Walls: 2–3
• Top/Bottom Layers: 3–4
• Speed: 40–60 mm/s
• Supports: OFF

Material Recommendations

• PLA (Best choice) → cleanest articulation
• PLA+ → stronger joints
• PETG → works well, use good cooling to avoid sticking
• ⚠️ TPU may fuse joints unless finely tuned

Print Tips

• Avoid over-squishing the first layer—this can fuse joints
• Let the print fully cool before flexing
• Gently work each joint loose after printing
• If needed, slightly reduce flow or first layer width for tighter printers

Scaling

• Designed for 100% scale
• Can scale down to ~80% depending on printer calibration
• Scaling up improves articulation and durability

Orientation

• Print flat on the build plate (default orientation)
• Do not rotate—optimized for bridging and joint clearance
