🚐 Truma Condensation Drain Pro – Ultra-Rugged & Anti-Stain
Tired of those annoying black streaks on your camper’s side? Or even worse, tired of flimsy 3D-printed drains that snap off during the first wash?
This Pro version has been completely redesigned from the ground up for those who demand maximum structural solidity and a clean motorhome.
While many designs online focus on saving material, this one is engineered for extreme durability:
💪 Reinforced Structure: Increased wall thickness at the attachment points to eliminate the chronic fragility found in "light" models.
🚿 Anti-Staining Geometry: Optimized curve to "throw" condensation away from the bodywork, permanently eliminating those ugly black streaks.
🛠 Professional Fitting: Designed for a millimetric fit on the standard Truma grill.
To guarantee the advertised strength, use these settings:
Parameter | Recommended Value |
|---|---|
Material | ASA (Best for UV/Heat) or PETG |
Infill | 25% (Gyroid) – The best strength-to-weight compromise |
Wall Loops | 4 Walls – Critical for structural integrity |
Supports | REQUIRED – "Tree" supports recommended for a flawless finish |
Layer Height | 0.20 mm |
Support Removal: Carefully remove the tree supports; the surface underneath will be clean and ready to go.
Indestructible Fix: To make the installation permanent and vibration-proof, apply a small drop of silicone or sealant (like Sikaflex) on the back of the mount before inserting it.
Mounting: Firmly press the drain onto the Truma grill. Once in place, the nozzle will be extremely secure.
