Knitting & Crochet Hat Add‑Ons — Brims & Ears Collection
Give your crocheted or knitted hats a unique, playful twist with this set of 3D‑printed add‑ons!
This collection brings together brims/visors and ears that can be embedded within the fabric, creating the impression they were part of the hat from the very beginning.
What’s included:
- Brims/visors: Three standard sizes (S, M, L) plus one extended M‑size brim designed for a flat cap style.
- Ears: Classic bear ears and sleek cat ears — perfect for kids, themed gifts, or anyone who loves a bit of fun in their accessories.
- Cut‑out brim/visor template: Ideal if you’re unsure of the exact size or shape you need.
This version can be cut directly to the desired shape and dimensions and used immediately — no reprint required.
Integration into hats:
The brim/visor and ears are designed to be hidden by crocheting or knitting around both sides, so they blend seamlessly into the hat.
For the best visual match, choose a filament that is transparent or the same color as your hat yarn.
These parts act as structural supports inside the knit or crochet fabric, giving the brim/visor and ears proper shape and stability.
Print & scaling tips:
- Brims/visors can be resized in X and Y to adjust width and depth, but keep Z (thickness) unchanged for consistent strength.
- For stronger brims/visors, orient them at a slight angle on the build plate with the edge that sits against the forehead resting flat on the bed.
- No supports required — all parts are optimized for FFF/FDM printing.
- 0.2 mm layer height works well; adaptive layer height may be used but is not essential.
- Recommended: use a brim (print adhesion) when printing the visor, as the contact area is narrow, use 3 perimeters for durability, and print ears with minimal infill for reduced weight.
Integration tip:
- For ears: creating a tight fabric “pocket” around them will enhance their shape and help them stand upright.
Material choice:
I made mine in PLA, which works well for casual use. A more durable material such as PETG is recommended, as it offers improved impact and weather resistance.
With just a bit of yarn and a printer, your handmade hat can go from simple to spectacular — a creative fusion of knitting, crochet, and 3D printing!
