It mounts the Hemera fairly high and well in between the guide rods. The "Nozzle High" customizer setting is the one I prefer.This is a lot easier to use than snap rings. The tiny holes in the bearing blocks are for brass wire to retain the bearings.You can get the Hemera STL from which will appear as a 'ghost' when OpenSCAD visualizes the mount.The plate has an integrated mount for a BLTouch bed sensor, tightly fit between the Hemera and the guide rods, putting it only 25 mm from the nozzle, with zero x offset.It is set up with OpenSCAD Customizer-compatible parameters at the top, making simple changes to the design as easy as filling in a dialog box. The design is in OpenSCAD, making it very easy to customize.This is particularly useful for high-quality, close-fitting bearings such as Igus Drylin, which have little tolerance for misalignment. Any rod spacing between 45 mm and 48 mm should work without even modifying the design. The design makes it fairly insensitive to the spacing between the guides rods on the printer, and also fairly robust against inaccuracies in the printing itself. The bottom bearing block is self-aligning.The bearing mounting blocks are printed directly onto the plate, greatly reducing the number of screws required to assemble, and the weight.The design of plate incorporates a number of critical features.

This project is to develop an very easy-to-use, 3D printable, adapter plate to mount an E3D Hemera Extruder on a 3d printer of the type similar to an Anet A8, Ender 3, or (probably) most Prusa I3-derived printers. Therefore, E3D Hemera it is not compatible with other Nema 17 motors and you'll not be able to swap the motor with either a compact but powerful/ slimline motor or other 3rd party motors.Hemera Extruder Mounting Plate for Anet A8 - type printersĭesigned by Marcus Mendenhall, February, 2020 Purpose *Please note* - whilst the custom motor is similar to a Nema 17, it isn’t a standard Nema 17. Hemera's heatsink design ensures airflow is diverted up and away from both the HotEnd and the heated bed, reducing the risk of warping and uneven stresses forming in the printed part. But trust E3D - the performance is second to none and also has a significant impact on printing normal materials such as PLA or PETG. You won’t truly ‘get’ the impact of the optimized constraint that Hermes provides until you’ve printed flexibles with it. Hemera constrains your filament like no other hotEnd/extruder combination. This is neat as it allows E3D to use the motor itself as part of the assembly and to add their own features for the user’s convenience, such as the mounting T-Slots. To achieve this, E3D has developed a custom motor, based on a NEMA17 frame, with their own faceplate designs. Hemera is a system of components designed to work seamlessly together as a single product. The round bottom of the profile strongly resists filament debris wedging into the drive gear and in almost all cases it’s self-cleaning as any debris simply falls off the teeth.Į3D set out to develop a compact extruder and HotEnd system with a reduced part-count. Individually CNC cutting each hobb allows for a round-bottomed root, with a tooth that curves upwards to a robust, sharp tip. Featuring dual drive gears, auto-loading compatibility, and fantastic grip strength providing a reliable extrusion system that minimizes slipping and grinding.Į3D Hemera is a dual-drive system with a hardened stainless steel drive train.
