Crochet Blocking Tool – 120 × 120 mm

I made this tool for my sister’s crochet projects and wanted to share it here in case it helps others too.

This blocking board measures 120 × 120 × 15 mm and comes with different thickness options in the file, so you can pick the one that works best for your yarn and projects.

Printing Tips:

• Best printed in ABS since it’s more resistant to heat and moisture. PLA absorbs water and can warp when blocking wet pieces.
• PETG also works as a middle option if you don’t have ABS.
• Designed for 5.8 mm wooden pegs, but you can also 3D print your own pegs sized 5.6–5.8 mm for a snug fit.
• Light sanding helps wooden pegs slide in smoothly.

Use Cases:

• Perfect for blocking granny squares, lace motifs, or small crochet pieces.
• For extra stability, place a foam pad underneath while pinning.

If you print this, please share your makes—I’d love to see how others use it!
