Fusion Revamp & PETG Prototype Prints
Budget: $30 – $250 USD
I have a simple Tinkercad model of three coaxial tubes—same inner diameter, varying outer diameters, arranged end-to-end—that represents an obsolete component I intend to replace through lost-foam casting. Before I can cast it, the CAD needs a quick cleanup: one transition currently has the wrong fillet. Please rebuild the part in fully-parametric form, correcting that fillet to an exact 0.3125-inch radius, so every dimension can be tweaked later if needed.
Once the geometry is sound, save two versions:
• the corrected original size
• a uniformly scaled copy at 105.5 %
Export both as native Fusion 360 files (.F3D), plus STEP for safety).
After the CAD stage, slice each version for a Prusa MK4 in PETG. PrusaSlicer project files (.3mf) are ideal; another slicer is fine as long as all settings remain editable. Suggested settings:
Layer Height: 0.20mm (Structural/Optimal)
Perimeters: Suggest 5 perimeters (for ultra-rigid side walls)
Top/Bottom Solid Layers: 5 layers minimum
Infill Density: 30% (70% internal air content)
Infill Pattern: Gyroid (for isotropic structural strength and dimensional stability)
Finally, print two physical copies of each size in PETG. Snap a clear JPEG of the filament label that shows brand and batch number, and include it with the hand-off alongside the slicer files.
Deliverables
– Corrected, fully-parametric Fusion file and STEP for original size
– Same file pair at 105.5 % scale
– Slicer project files for each size
– Two PETG prints of each size (total four)
– JPEG of filament label / batch
Acceptance criteria
• Fillet radius reads exactly 0.3125 in in CAD
• Inner diameter remains unchanged through scaling
• Both prints are clean, dimensionally accurate, and free of layer separation
If anything is unclear, just let me know—I can provide added measurements or photos of the legacy part on request. I have detailed JPEGs, dimension screenshots, and a 3/4 view of the Tinkercad workspace ready to share with the selected freelancer. I can also export the tinker cad file if it is of use.
