The LIS3DH is a very popular low power triple-axis accelerometer. It's low-cost, but has just about every 'extra' you'd want in an accelerometer: Three-axis sensing, 10-bit precision ±2g/±4g/±8g/±16g selectable scaling Both I2C (2 possible addresses) and SPI interface options Interrupt output Multiple data rate options 1 Hz to 5Khz As low as...

These flex couplers are ideal for attaching a 5mm threaded rod to standard NEMA 17 stepper motors. They feature two grub screws per shaft, so they grip strongly and won't slip! Flexible couplers are great because they allow for slight misalignments in the coupled shafts - so even if your RepRap isn't...

These displays were used in old Nokia 5110/3310 mobile phones (before the smartphone fad turned every mobile phone into a TV). It's an 84x48 pixel monochrome LCD display. These displays are small, only about 1.5" diagonal, but very readable and come with a white backlight. This display is made of 84x48 individual...

Nylon nuts — they're lightweight, don't rust, and are electrically insulating. They're strong too! This is a pack of 25 nylon M3 nuts. Great for hobbyist and RC use. Specifications Material: Nylon Thread size: M3 Pack quantity: 25

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 stepper motors are lightweight and compact, but still provide plenty of torque - we've found them to be perfect for everyday printer duty. The motor's shaft has been ground flat, making it easy to get a good grip with a pulley, drive gear - or anything that uses a grub screw, really. Another handy...

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 16-tooth profile. These pulleys include 2 M3 grub screws for a strong grip, and come...

These precision shims have an outer diameter of 13mm, an inner diameter of 8mm and are 1mm thick. They're a great match for 8mm diameter lead screws, and are one of the components needed along with our lock-collars and threaded rod plates to create a sturdy linear axis - see the included drawing...

These fans run on brushless bearings, meaning they run quietly and have a long lifespan. They are lightweight and can be mounted to a moving carriage without impacting its performance. They are ideal for cooling 3D printer hotends, and are also great for cooling the print itself (if you want to print...

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...

Protoboard Plus is designed to make prototyping electronics projects easier. Unlike regular protoboards made from FR2, Protoboard Plus is a full FR4 PCB - making it sturdier, and more forgiving of hot soldering-iron tips! M3 screw holes make Protoboard Plus easy to fix in place. Each Protoboard Plus incorporates two rails, ideal...

Add some jazz & pizazz to your project with a colour touchscreen LCD. This TFT display is 2.4" diagonal with a bright (4 white-LED) backlight and it's colourful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive...

These high quality nickel plated springs have been designed specifically for 3D printer use. They are manufactured from carbon steel, and they hold their elasticity well - these springs don't wear out easy! They are perfect for maintaining extruder idler tension, and they also work brilliantly for supporting the printer bed....

These nut blocks are one of the easiest ways to integrate a lead screw driven axis into your build! On one side they have recesses for our M5 low profile screws, and on the other recesses for M5 hex locknuts - this allows these blocks to be fairly flexible in how they're...
