Wow - heated bed conversion kit for UM2GO! Includes everything you need: Peel-and-stick heater with temp sensor, firmware. Instructions and more details are here.

This is version 2 of the kit which is cheaper, easier to install (version 1 required installing a new nozzle heater) and it smells better (I found the silicone version was a little stinky when printing ABS - although the ABS also smells bad). Learn More

This needs to be paired with a 1.75mm hardcore - email us for details: thegr5store@gmail.com

This feeder expects a 1/4 inch (6.35mm) O.D. bowden tube - not the typical 4mm O.D. bowden tube for 1.75mm filament.

.8mm JET RSB Nozzle. Compatible with e3d v6 nozzles designed for 3mm filament. Learn More

Convert to 1.75mm! This is experimental. I haven't tried it - I don't know if anyone has. I'm not sure if changing this part alone is enough - it seems like it should be as on the UM2 you only have to change the heating block and the teflon part - certainly you don't need to change the bowden. So I think it will work.

Replaces Ultimaker Original (not Ultimaker2) teflon part but this part can print at 255C continuous for years. Never replace your teflon part again. This is made of teflon but it's a high temperature teflon. Learn More

1mm nozzle for really fast prints. If you plan to do .5mm layer height it's recommended to also get a 35W or 40W heater.

These nozzles are e3dv6 compatible meaning they work with all versions of the Olsson block including the one on the Ultimaker 2+. They work on other reprap printers also.

The JET RSB have a revised tip angle, revised jet shoulder width and revised internal geometry, with a gentle slope leading down to the exit. They are also slippery inside, due to a special treatment.

These new nozzles are meant for Speed! Plastic will flow more easily than in most other nozzles. Atomic pulls work very well! The inside geometry makes it much harder for plastic to “hide in the corners”, so changing color/filament type will be quicker and safer.

For "3mm" filament (not 1.75mm filament). Learn More
