How to make a jersey keychain
- Pick the shirt: a cricket polo with a collar, or a round-neck football shirt.
- Type the name and number for the back. They are changed to capitals; long names shrink to fit across the shoulders.
- Choose the trim – collar, sleeve stripes and side stripes – and the size: mini 40 mm, standard 50 mm or large 65 mm tall.
- Download one STL, or the multi-colour ZIP for AMS / MMU printers.
Colour tips
| Printer | What to do |
|---|---|
| Single colour + one filament change | Print the shirt in your team colour and change filament at the height shown under the preview (the shirt thickness, 2.4 mm by default). Name, number and trim come out in the second colour – white or yellow on blue, white on red or maroon, black on yellow. |
| AMS, MMU or tool-changer | Load the three STLs from the ZIP as one object and give the trim its own third colour. |
| Contrast | Pick colours with strong contrast so the number reads from across the room – dark shirt, light letters, or the other way round. |
Recommended print settings
| Setting | Value |
|---|---|
| Material | PLA or PETG |
| Layer height | 0.12–0.2 mm (finer for the mini size and long names) |

| Supports | None. Print flat, back of the shirt up. |
Gifts for players, teams and fans
Jersey keychains make simple, personal gifts: one for every player in a school or club team with their own name and number, a thank-you for a coach, prizes for a school sports day, or a fan keychain during IPL or World Cup season in your favourite colours. Print a whole squad by changing the name and number between prints. For plain name tags, try the name keychain generator, and for a car or bike, the number plate keychain generator.
Frequently asked questions
Can I sell the jersey keychains I print?
Yes. The STL files you make here are yours to print, give away or sell, with no licence fee. The shirts are generic outlines, so add your own colours, names and numbers – but don’t add team crests, league logos or sponsor names you don’t have permission to use.
Is this affiliated with any team or league?
No. 3D MakerBench is not affiliated with, endorsed by or connected to any cricket or football team, league, board or kit maker. The shirt shapes are plain, generic designs and no official kits are copied.
How do I print the name and number in another colour?
On a single-colour printer, add a filament change (pause) at the height shown under the preview: the shirt prints in the first colour, and the name, number and trim in the second. With AMS, MMU or a tool-changer, download the multi-colour ZIP – shirt, name + number, and trim are separate STLs that line up, so the trim can be a third colour. On Bambu Studio or OrcaSlicer it is even simpler: download the Colour 3MF – one file in which every colour is already a part set to its own filament (1, 2, 3…), so it is ready to print on an AMS.
How long can the name be?
Up to 10 letters. Longer names shrink and narrow to fit across the shoulders; on the mini size, keep names short so the letters stay at least 3 mm tall. The number can have up to 3 digits.
What is the difference between the cricket and football shirt?
The cricket shirt is a polo with a stand-up collar at the back of the neck and a curved shirt-tail hem. The football shirt has a round crew neck and a straight hem. Both have short sleeves and a key-ring loop at the collar.
Will it be strong enough for keys?
Yes, printed flat in PLA or PETG with 3 walls. The ring loop sits above the collar with 2.4 mm of plastic around the hole; a 2.4 mm shirt (the default) is about as thick as most printed keychains.
