If you spend any amount of time 3D printing, you quickly realize that the printer itself is only part of the setup. Having a few good accessories on hand can make printing easier, help prevent common problems, and save you from having to stop a project when something goes wrong.

Whether you're new to 3D printing or have been printing for years, these are five accessories worth having in your workshop.

1. A G10 3D Printer Build Plate

Your build plate is one of the most important parts of your 3D printer. If the first layer doesn't stick properly, the rest of the print doesn't have much of a chance.

A G10 build plate is a popular option for 3D printing because of its combination of durability and reliable print adhesion. G10, also known as Garolite, is a fiberglass composite material that can handle the heat required for many 3D printing applications.

One of the biggest advantages of a good G10 build surface is being able to get a solid first layer without constantly fighting adhesion issues. Once the plate cools, prints can also be easier to remove.

If you've been dealing with prints lifting at the corners, poor first-layer adhesion, or inconsistent results, your build surface is a good place to start.

Our G10 Fiberglass Garolite 3D Printer Build Plates are available in different sizes to fit a variety of printers.

A good build plate isn't something you should have to fight with every time you print.

2. A Build Plate Made for Your Specific Printer

Not every build plate is going to fit every 3D printer. If you have a newer large-format printer, finding an aftermarket build surface that is actually designed for your machine can make a big difference.

For Bambu Lab H2S and H2D owners, we offer a G10 build plate specifically designed for these printers.

The large build area on these printers makes having a dependable printing surface especially important. A failed print on a large-format machine can mean hours of wasted time and filament.

If you're printing larger functional parts, prototypes, or engineering materials, having a reliable build surface is one upgrade worth considering.

Always check your printer's dimensions and compatibility before ordering a replacement or aftermarket build plate.

3. A 3D Printer Nozzle Cleaning Tool

Eventually, you're probably going to deal with a clogged nozzle. It's one of those things that comes with 3D printing.

You may notice filament isn't coming out correctly, extrusion has become inconsistent, or your prints suddenly aren't looking like they normally do. Before assuming something is seriously wrong with your printer, it's worth checking the nozzle.

Our 3D Printer Extruder Filament Declogging & Cleaning Tool includes five steel cleaning rods for helping clear filament blockages from the nozzle.

It's a small tool, but it's one we recommend keeping close to your printer. When a clog happens in the middle of a project, you'll be glad you have one.

Why keep a nozzle cleaning tool nearby?

Helps clear clogged or partially clogged nozzles
Useful for routine nozzle maintenance
Five steel cleaning rods included
Easy to keep in your printer tool kit
Takes up very little space

It's one of those inexpensive 3D printer accessories that can save you a lot of frustration.

4. 3M 468MP Adhesive Transfer Sheets

Adhesive sheets aren't something every 3D printer owner will need, but if you're working on custom setups, repairs, or DIY projects, they can come in handy.

Our 3M 468MP Double-Sided Adhesive Transfer Tape Sheets come in a 12" x 12" size, giving you plenty of material to work with.

The sheets can be cut to the size you need, making them useful for a variety of maker and 3D printing projects.

If you like modifying your equipment, experimenting with different surfaces, or building your own solutions, having a good adhesive transfer sheet in your workshop is worth it.

5. A Spare Build Plate

Here's one that doesn't seem necessary—until you need it.

If you print regularly, having a spare 3D printer build plate can save you time. Instead of waiting for your only plate to cool, clean, or be prepared for the next print, you can simply swap it out and keep going.

A spare build plate is also useful if you like experimenting with different printing surfaces or materials.

We offer several G10 options, including our standard G10 Garolite build plates , blemished G10 plates, and the Bambu Lab H2S/H2D G10 build plate.

And if you print large models, keeping a backup build plate on hand can be especially helpful. Nobody wants to discover a problem with their build surface right before starting a long print.

Build Your 3D Printing Tool Kit

You don't need to buy every 3D printing accessory you see online. Start with the things that solve problems you actually run into.

A dependable G10 build plate can help with your first layer. A 3D printer nozzle cleaning tool can help when filament gets stuck. Adhesive transfer sheets can come in handy for DIY projects, and a spare build plate can keep you printing when your primary plate needs attention.

The goal isn't to have a workshop full of gadgets. It's to have the right tools available when you need them.

At Wilbur's Finest, we make practical tools and accessories for people who like to build, print, repair, and create. We're constantly adding products that we think are actually useful—not just products that take up space in your toolbox.
