I decided to print this and the first print didn&#39;t feel safe enough for larger Deer Skulls to me. So I decided to play around and print some more and came up with the below.  # 🧱 PETG (Bambu P1S – Textured PEI Optimized Profile) ✅ Tuned for functional parts, brackets, and wall hooks   🔧 Tested with: **Bambu Lab P1S** + **Textured PEI Plate**   🧴 Adhesion Aid: *Thin Elmer’s glue layer recommended*  ---## 🧪 Filament Settings - **Type:** PETG (Generic / Bambu)   - **Flow Ratio:** 1.00–1.02   - **Diameter:** 1.75 mm   - **Nozzle Temp:** 250 °C (first layer) → 245 °C (others)   - **Bed Temp:** 85 °C (first) → 80 °C (others)   - **Cooling:** 0–15 % for first 3–5 layers, max 55–60 %   - **Adaptive Volumetric Speed:** Enabled   - **Max Volumetric Speed:** 12 mm³/s  ---## 🌬️ Cooling - First 3 layers: **0–15 % fan speed**   - Min fan threshold: **25 % @ 30 s**   - Max fan threshold: **55 % @ 12 s**   - Overhang fan speed: **70 %**   - Keep fan always on: ✅   - Auxiliary cooling fan: **0 %** (off for PETG)---## 🧵 Retraction - **Distance:** 0.8 mm   - **Retraction Speed:** 25 mm/s   - **Deretraction Speed:** 20 mm/s   - **Z-Hop:** 0.2 mm   - **Retract When Change Layer:** ✅ *Forced*   - **Wipe While Retracting:** ✅ *Forced*   - **Wipe Distance:** 2.0 mm   - **Travel Distance Threshold:** 1.0 mm  ---## ⚙️ Quality (Modifier Block – Reinforced Region) - **Outer Wall:** 0.42 mm   - **Inner Wall:** 0.45 mm   - **Top Surface:** 0.42 mm   - **Sparse Infill:** 0.48 mm   - **Internal Solid Infill:** 0.45 mm   - **Smart Scarf Seam:** Enabled   - **Scarf Steps:** 10   - **Scarf Joint for Inner Walls:** Enabled   - **Ironing:** Disabled   - **Order of Walls:** Outer → Inner   - **Smooth Speed Discontinuity:** Enabled   - **Smooth Coefficient:** 150  ---## 💪 Strength - **Wall Loops:** 6   - **Top Layers:** 5   - **Bottom Layers:** 5   - **Top/Bottom Pattern:** Monotonic or Rectilinear   - **Internal Solid Pattern:** Rectilinear   - **Infill Density:** 75 % Gyroid (global)   - **Modifier Block Infill:** 100 % Rectilinear (solid reinforcement)   - **Infill/Wall Overlap:** 15 %   - **Ensure Vertical Shell Thickness:** Enabled  ---## ⚡ Speed | Area | Speed (mm/s) | |------|---------------| | Outer Wall | 100 | | Inner Wall | 170 | | Sparse Infill | 180 | | Solid Infill | 150 | | Top Surface | 80 | | Bridges | 35 | | Gap Infill | 120 |- **Slow Down for Overhangs:** Enabled   - **Overhang Speed Gradient:** 50 → 10 mm/s   - **Acceleration:** 3000 mm/s² (default)   - **External Walls Accel:** 1500 mm/s²   - **Travel Accel:** 5000 mm/s²  ---## 🧩 Modifier Block (Reinforced Arm) **Purpose:** Makes the hook arm 100 % solid for max strength.   - Add Modifier → **Cube**   - Cover entire hook arm + base joint   - Add Process → set these overrides:    - **Infill Density:** 100 %    - **Infill Pattern:** Rectilinear    - **Wall Loops:** 6    - **Top/Bottom Layers:** 6   - Name the process: *“Reinforced Arm”*  ---## 🧴 Adhesion Notes - Clean textured PEI with **warm water + dish soap**, *not IPA only*.   - Apply a thin **Elmer’s glue film** for reliable grip + easy release.   - Let bed cool fully before removal; PETG will pop off on its own.  ---## 📊 Performance Summary | Property | Rating | |-----------|---------| | Adhesion | 🔥 Excellent (with glue film) | | Strength | 🧱 Very High | | Layer Bonding | ⚡ Excellent | | Stringing | ⚙️ Minimal | | Surface Finish | ✨ Smooth / Glossy | | Print Time | ⏱ Moderate | | Ideal Use | Wall hooks, brackets, mounts, enclosures |---## 🧠 Notes Profile tuned for **PETG functional prints** on **Bambu P1S** using the **Textured PEI Plate**.   Focuses on **strength, consistency, and adhesion reliability** for load-bearing parts.   Includes **modifier block reinforcement** for high-stress regions.  &gt; 💡 Verified on “Skull Wall Hook” (by tanman).   &gt; Survived static load tests up to ~30 lb (safe working load ≈ 10–12 lb with SF = 3–4).  ---👤 **Profile by:** Snarkywolf 🧰 **Tested Filaments:** Bambu PETG / Overture PETG / eSun PETG+   🏗️ **Printer:** Bambu Lab P1S   🪶 **Plate:** Textured PEI   🌡️ **Enclosure:** Closed

-Oriented the hook for no support use as original uses trees supports due to orientation.-Cut infil to 25 percent to save on filmament use and still keep durability.

0.2mm layer, 3 walls, 25% infill no supports oriented 

Display your skull/european mount on the wall with this! I attach them using interior wood screws into studs, and the spacing allows easy access with a screw driver or long drill bit. I&#39;ve used these with three whitetail deer skulls with no issues. The 45° angle seems to look the best. I&#39;m not sure how much weight they will hold, so use caution if using with larger animal skulls. I plan on reprinting mine with grey after I paint my walls to blend in better!
