These microswitches make excellent endstops for any RepRap. Their small size makes them ideal for more compact builds – such as a Prusa Mendel, where they are small enough to let you take full advantage of each axis. Each switch has two holes that will suit either small cable ties or...

These stepper drivers are built around Allegro's A4988 stepper driver IC. This is one of the most common and widespread stepper driver ICs used in 3D printer electronics and is commonly selected because of its balance of performance, cost, and reliability. These drivers are made in the Pololu-style 'stepstick' footprint....

These stepper drivers are built around Trinamic's TMC2130 stepper driver IC. TMC2130 drivers have a number of advantages, most notable of which is their quiet operation due to Trinamic's stealthChop technology. Note that TMC2130 stepper drivers are configured via SPI, and that SPI control is required to fully configure many of...

E3D's latest HotEnds feature fancy detachable cables for their fans and thermistors, making wiring your 3D printer easier than ever. But what do you do if you need a longer cable for your ultimate printer build? Or need another set of cables for HotEnd hot-swapping goodness? Fear not, for we've got...

Looking for a replacement extruder gear for your Creality CR-10 printer? Then look no further! These brass gears feature 40 teeth, and are secured in place by two grub screws. Suitable for the Creality CR-10's extruder, along with many other makes and models. Specifications Material: Brass Inner Bore: 5mm External Diameter:...

These endstops are easy to mount, and even easier to connect. They come with a cable to hook them straight up to a RAMPS board, and feature four mounting holes. Easy! Compared to regular microswitches, these PCB mounted switches have onboard LEDs - making it easy to see if your endstops are being...

Ever had a spool of filament run out mid-print? If you're lucky, you knew you were going to run out and had to sit there waiting for it to happen, so that you could swap in a new spool. If you're unlucky, it ran out without you knowing about it - and now...

These stepper drivers are built around Trinamic's TMC2100 stepper driver IC. TMC2100 drivers have a number of advantages, most notable of which is their quiet operation due to Trinamic's stealthChop technology. These drivers are made in the Pololu-style 'stepstick' footprint. They are compatible with any control board that accepts this footprint,...

These stepper drivers are built around Trinamic's TMC2209 stepper driver IC. TMC2209 drivers have a number of advantages, most notable of which is their quiet operation due to Trinamic's stealthChop technology. Note that TMC2209 stepper drivers are configured via UART, and that UART control is required to fully configure many of...

These high-quality aluminium GT2 pulleys fit a 5mm shaft, making them ideal for use with NEMA-17 stepper motors or M5 mounting hardware. They will work with any standard GT2 belt up to 7mm in width, and feature a 36-tooth profile. These pulleys include 2 M3 grub screws for a strong grip, and come with...

If you've ever needed to de-solder something, you know what a pain it can be without the right tools. This vacuum 'Solder Sucker' makes it easy - it simply sucks up the excess solder, letting you get on with the job. Featuring sturdy construction and a metal grip, these are reliable and easy...

Got a servo motor? Need a longer cable? Fear not, we have the solution! These cables are clearly marked in red, black and white for the different wires. They are male to female and will extend a standard 3-pin servo cable. Specifications Length: 150/300/500mm Gauge: 26AWG Pin Spacing: 2.54mm (0.1")

These high quality aluminium GT2 pulleys fit a 5mm shaft, making them ideal for use with NEMA-17 stepper motors or M5 mounting hardware. They will work with any standard GT2 belt up to 7mm in width, and feature a 60-tooth profile. These pulleys include 2 M4 grub screws for a strong grip, and come...

Heatshrink is handy whenever you're doing any wiring! These helpful packs include six different sizes of heatshrink in both red and black. Heatshrink is helpful in any electronics project. These kits are great when putting a 3D printer together - but they'd also do a good job for hobby / RC electronics - or anywhere...

Note: Due to the primary component in these boards being discontinued, we regret we are not currently able to produce more. We are hoping to make these available again when the necessary components are available. Our apologies! These magnetic encoder modules let you add on closed-loop control to existing 3D...

The Smart Controller is a graphical user interface to control your 3D printer without the need for a direct computer connection. The Smart Controller has an integrated SD card reader, a rotary encoder with push button and a 20x4 line LCD display, allowing all types of actions from calibration to axis movements and direct...
