How to Choose a UV Printer Jig (eufyMake E1 and xTool Omni)
I design and sell jigs for both UV printers in this guide, so keep that in mind as you read.
If you've ever lined up blanks on a UV printer bed by eye, you know how it goes. A ruler, a strip of tape, a lot of squinting, and then one coin prints a hair off center and lands in the scrap bin. Do that across a 20-piece order and the wasted blanks and ink add up fast.
A good UV printer jig fixes that. It holds every blank in the same spot and at the same height, it comes with a template file that already matches those spots, and it goes back on the bed the same way every time you swap it. I run a eufyMake E1 and an xTool Omni (O1) in my shop and make jigs for both, so this is how I'd pick one, whoever you end up buying from.
The short version
Same spot, same height, and a template file that matches.
Any UV printer
Pick a jig made for your exact machine, bed and blank, with a matching template file.
On the eufyMake E1
Pair your jigs with an alignment system so Zero Point lines up after every swap.
On the xTool Omni
The scanner handles placement. An alignment system is a convenience, not a must.
Seven things to check
What makes a good UV printer jig
It puts every blank in the same spot, every time
This is the whole job. Each item should sit in a pocket shaped to it, so it can't slide or turn. If you can pull a blank out, drop a new one in and print the same layout without touching your software, the jig is working.
The reprint test
In my own testing on the E1, I pulled a heart-shaped pet tag out, put it back and reprinted it four times over. You can't see any shift in the design.
It comes with a template file that matches
Without a matching file, you still have to measure the pockets and build the layout yourself. Every jig I sell ships with a template file that matches its pockets. On the E1 that's a eufyMake template file. On the Omni, my Golf Ball Jig, for example, comes with an alignment template file and an xTool Studio (.xs) file you can open and print from.
It holds every print face at the same height
eufyMake says to keep print faces on the E1 within 2 mm of each other, and in my shop I treat about 3 mm as the edge before prints go soft. A good jig seats every item so the tops line up across the whole tray.
It fits your machine and your bed
The E1 and the Omni each come with two beds, and a jig is built for one of them. My E1 jigs are built for the E1 mini bed, and my Omni jigs are built for the Omni Standard bed. Neither fits the large bed on its machine. Before you buy any jig, check which machine and which bed it was designed for.
It's made from something that holds its shape
My jigs are 3D printed plastic. Printing is what lets a pocket be shaped to one exact item: a golf ball, a pen, a 40mm coin. Check the item size on the listing before you order, because a pocket shaped for one blank won't hold a different one the same way.
Its capacity matches your batch size
Pick a jig that fills a tray for the orders you actually get. Bed size sets the ceiling: the Omni Standard bed is 122 mm front to back against 90 mm on the E1 mini bed, and my Omni Golf Ball Jig holds 20 balls where my E1 version holds 12. Layout matters too. On the Omni, a staggered three-row layout fits 20 balls where a straight grid manages 14.
A single jig, or a jig plus an alignment system
A jig on its own still has to be placed on the bed. If it lands a little rotated or off from last time, the whole tray is off with it. An alignment system gives every jig a fixed home, so you can swap jigs and keep printing. How much you need one depends on your machine.
Every option has a place
Your options, compared
A made-for-the-item jig isn't the only way to hold blanks, and every option below has a place.
Lining items up by eye with tape
Best for: a one-off gift.
- Same spot: only as good as your eye
- Template file: you build it
Free jig files you 3D print yourself
Best for: tinkerers with a 3D printer and time to test.
- Same spot: only if you square it up by hand
- Template file: you build and line up your own
Silicone grid or clip mat
Best for: odd shapes and items that change every job.
- Same spot: holds items steady; you set the layout and set it again when the item changes
- Template file: you place your art for each setup
Ready-made jigs from other sellers
Best for: items nobody else makes a jig for.
- Same spot: varies by maker
- Template file: check the listing
The only kind I make
Made-for-the-item jig plus an alignment system
Best for: shops printing the same item by the tray.
- Same spot: yes, every swap
- Template file: included
If you print something different every day, a grid or clip mat might be all you need. If you own a 3D printer and enjoy tinkering, free files can work too. Where a made-for-the-item jig earns its keep is the tenth and fiftieth tray of the same item.
When you need one
You don't need a jig for a one-off gift. You need one the moment you want the same result twice.
Jigs for the eufyMake E1
Needs: a fixed home for every jig, because Zero Point prints at fixed coordinates
The E1's camera reads the corner of the stock adhesive mat, and Zero Point prints at fixed coordinates from that corner. A batch only lines up if your jig sits in exactly the same spot every time, and the stock bed gives you nothing to register a jig against. That's the number one frustration I hear from E1 owners, and I hit the same wall myself.
It's why I spent two to three months designing the Jig Alignment System for the eufyMake E1. Two pieces clip onto the mini bed and give every Samcraft E1 jig a hard edge to sit against. Drop a jig in, print, pull it out, drop in the next one, and Zero Point lines up every time.
My E1 jigs are made for the mini bed, which eufyMake lists at 330 x 90 mm of print area. They're $24.99 each, and there are more than 30 of them: coins, dice, golf balls, pens and pencils, coasters, business cards, patches, bottle openers, metal wallets, dog tags and more. The alignment system is $24.99 too. Want the full setup? Read the E1 accessories I'd add first.
Jigs for the xTool Omni
Needs: jigs that land square on a swap; the scanner handles the rest
The Omni works differently. It scans the bed with a sensor under the print carriage instead of a camera in the lid, and xTool publishes its positioning accuracy at ±0.2 mm. On my machine, prints have landed dead on in the center of the bed and in the corner. What the scanner can't do is stop a jig from landing slightly rotated or off-center when you swap it.
So you don't need my Jig Alignment System for the xTool Omni to print with my jigs. It's a convenience, and that's how I'd judge it. Two pieces slide over the ends of the Standard bed with no tools and no calibration, and every Samcraft Omni jig drops in square and centered, since they all share the same footprint.
My Omni jigs are made for the Standard bed, which xTool lists at 330 x 122 mm of print area. They're $29.99 each, and there are more than 40 of them, from golf balls and 18-pen trays to pet tags, hat brim clips and mahjong tiles. The alignment system is $19.99 on its own, or $9.99 added to an Omni jig order.
The Jig Size FatMat is a silicone mat that fits the Omni Standard Bed and drops into the alignment system for flat work between jig runs.

Before you order
A quick checklist before you buy
- Is it built for your exact machine and bed?
- Does a matching template file come with it?
- Is the pocket sized for your exact blank?
- Does it hold every print face at the same height?
- Does the capacity fit the orders you actually get?
- Will it go back in the same spot after every swap?

Asked and answered
Common questions
What is the best jig for a UV printer?
The best UV printer jig is made for your exact machine and bed, has a pocket shaped to your item, comes with a matching template file, and lands in the same spot every time you swap it. For batch work on a eufyMake E1 or xTool Omni, that means a made-for-the-item jig paired with an alignment system.
Do I need a jig to use a UV printer?
Not for a one-off print. You need one the moment you want the same result twice. A jig holds each blank in the same spot and at the same height, so a layout you set up once keeps working across the whole batch.
What are UV printer jigs made of?
Mine are 3D printed plastic, which lets each pocket be shaped to one exact item, like a golf ball, a pen or a 40mm coin.
Does the xTool Omni need a jig alignment system?
No. The Omni's scanner and xTool Studio handle placement well on their own. On the Omni an alignment system is a convenience that makes every jig land square and centered on the Standard bed. On the eufyMake E1 it matters more, because Zero Point prints at fixed coordinates and the stock bed gives a jig nothing to sit against.
Do Samcraft jigs fit the large bed?
No. My eufyMake E1 jigs and E1 Jig Alignment System are built for the E1 mini bed. My xTool Omni jigs and Omni Jig Alignment System are built for the Omni Standard bed.
Do UV printer jigs come with template files?
Mine do. Every Samcraft jig ships with a template file that matches its pockets, so you drop your art in and print. If you buy a jig anywhere else, check the listing for a template file, or plan on building the layout yourself.
