We stock a range of hardware to help the do-it-yourselfer build 3D printers. We’ll tell you exactly how to make these yourself from scratch if you really want to. Customers outside New Zealand do not pay GST
Extruder Hot End
The ingredients are: An 25mm PTFE rod, 40mm M6 brass bolt for the heater barrel that we drill out to match 3mm or 1.75mm filament, M6 brass dome nut machined into the 0.45mm nozzle, 4 Ohms of nichrome wire and a 100k thermistor.
We supply fire cement for changing thermistors, and PTFE “thread seal” tape on request. We can do 18mm PTFE but strongly recommend the more robust 25mm fibre re-enforced PTFE – we’ll even print you a new 25mm extruder body.
Wade Extruder Hobbed Rod
These are the drive rods for a Wade-type extruder; the part that grips and pushes the filament into the Hot End. The adjustable one we make is a 75mm M8 rod with an M4 hob 33mm from one end, slotted to avoid plastic build-up. As the whole thing is threaded you can move nuts around to align the hobbed bit with your extruder’s filament. Normally we supply them for 3mm filament, but make 1.75mm to order. Currently not on the website but if you are interested just email us.
Assembled Wade Extruder
For those unable or unwilling to put one together, we can supply a fully assembled Wade-type 3mm extruder using a NEMA17 stepper and made to fit two M4 50mm mounting holes .
We import generic Arduino Mega 1280 and Arduino Nano 328 clones from China and sell them off really cheaply to get you started. Available via email order.
Drive Belts and Gears
We used to stock E-Sky 800mm model helicopter belts for use as RepRap drive belts, but they have been phased out for T5 6mm wide Polyurethane belts and GT2 fibre-backed 6mm belts which we sell by the metre, as well as their respective pulleys.
608 “Skate” Bearings
The archetypal bearing for M8 studding and 8mm round rod, used on RepRaps throughout the ages.
Printed RepRap Parts
Not a regular stock item because designs change all the time, but do ask. We may well have a complete set of printed parts of our own printers lying about as we are constantly prototyping new designs.
Let’s be honest – we sometimes overdrive our stepper motors slightly in the pursuit of speed. Putting a little video card fan on the back of the stepper will drop its temperature by about 20C and stops it from melting its way out of your RepRap!
We don’t sell those, and we don’t sell stepper drivers either I’m afraid. A lot of users have Pololu stepper driver modules, which are theoretically beefier but the EasyDrivers are available locally and work well for me.
