QR codes on 3D prints: a quick guide to tags that scan

 Q: Can a 3D-printed QR code scan with a phone?

A: Yes, if the contrast is strong and the code is big enough. Aim for 25 mm wide or more.

Steps:

1. Type your link in Shapiful and make the QR code.

2. Put it on a flat face or on a small tag with a hole for a string.

3. Download the STL and print it.

4. Scan it with your phone before you use it.

Tips: leave a clear border of about four modules, and use two colors or paint to raise the contrast. QR tags work well on bins, plant stakes, toy sets and gift tags.

Toy box labels you can 3D print: a simple guide

 Q: How do I keep a building-toy set tidy? A: Label each box and each part bin. Printed tags last longer than paper. What you need: a 3D printer and a file with text. Shapiful makes the file in your browser. Step 1: Type the label, for example "Wheels", "Gears" or "Red bricks". Step 2: Choose a tag with a hole for a string, or a flat strip to glue on. Step 3: Download the STL and print it. Step 4: Add raised braille on a second line if a child who reads braille uses the box. Why it helps: children find parts faster and put them back in the right place. Tidying up becomes a game.

How to make a 3D-printable braille label

 Can I print braille at home? Yes. A normal FDM printer can print raised dots, if the dot size and spacing are right. What you need: a 3D printer, a slicer, and a file with correct braille dots. Steps: 1. Type the word in Shapiful and choose the braille option. 2. Choose a base shape: a tag, a strip, or a sign with holes for screws. 3. Download the STL file. 4. Print with a layer height of 0.12 to 0.2 mm, so the dots stay smooth. 5. Touch the label with a fingertip before you fix it in place. Good first projects: a drawer label, a cable tag, a sign for a room door. Make one here: https://www.shapiful.com/?utm_source=blogger&utm_medium=social&utm_campaign=round1_oct26
