🖨️ Optimized for FDM Printers! 🖨️
This mask was born for FDM printing.
Intelligent Splitting: By splitting the mask into front and back, we've dramatically reduced the need for complex, messy internal supports. You get a cleaner print, faster.
Strength: The 2-part design allows you to print with strong walls, making the final mask durable enough for any Halloween party.
Resin Option: This model can also be printed on large-format resin printers (like Saturn, Jupiter, etc.) for a truly movie-quality prop with breathtaking detail.
⚙️ Manufacturing & Assembly Instructions (CRITICAL!) ⚙️
To complete your mask, you will need a few extra parts.
Hardware Required:
6x Neodymium Magnets (Size: 6mm x 3mm)
1x Flexible Strap (Elastic banding, about 1-inch or 25mm wide)
Super Glue (Cyanoacrylate)
Print Settings (FDM):
Layer Height: 0.16mm - 0.20mm (0.16mm will capture the cracks better).
Infill: 10-15% is sufficient.
Supports: Tree (Auto) supports are ESSENTIAL.
Support Placement: Everywhere. The nose, chin, and hair will need it.
Bed Adhesion: A Brim (10-15 lines) is highly recommended to prevent warping on such a tall, large print.
Assembly Instructions:
PRINT THE fit_test.stl FIRST! (Critical Step!) This small file prints in ~20 minutes. Hold it against your head to check the overall size.
Does it feel right? Print all main parts at 100% scale.
Too small/big? Scale the Mask_front, Mask_back, and Stripe_loop files all by the same percentage (e.g., 105% or 95%) in your slicer for a custom fit. This test saves you from wasting an entire roll of filament on a mask that doesn't fit.
Print all main parts. Carefully remove all Tree Supports, especially from the nose and eye sockets.
Install Magnets:
Test polarity! Mark one side of all 6 magnets with a pen.
Glue 3 magnets into the Mask_front slots (e.g., "marked side up").
Glue the other 3 magnets into the Mask_back slots, ensuring they attract the front half (e.g., "marked side down"). BE CAREFUL with glue and polarity.
Attach Loops: Glue the two Stripe_loop.stl parts to the inside of the mask. You can place them anywhere you like for the most comfortable fit.
Add Strap: Thread your flexible strap through the loops.
(Optional) Add foam padding to the inside for extra comfort
⚠️ CRITICAL SLICING INSTRUCTION - PLEASE READ! ⚠️
When you load the pennywise_Mask_front.stl or pennywise_Mask_back.stl into your slicer software (like Cura, PrusaSlicer, etc.), you may see a pop-up message that says the model has errors and needs to be "repaired".
DO NOT REPAIR THE MODEL. Please IGNORE or DECLINE this message.
Why? This is a false positive. The slicer is detecting the precision-engineered magnet slots (the holes) as "errors". If you click "Repair", the software will "fix" the file by FILLING IN and DESTROYING these essential slots, and you will not be able to install your magnets.
The file is intentionally designed this way, has been fully tested, and will print perfectly. Just ignore the warning and proceed to slice.
