# E3D Hemera + Robo3D R1(+) = #RoboHemera

Here are all of the parts you need to get started creating your very own #RoboHemera extruder. I've printed mine in Fillamentum Neon Orange Transparent CPE HG100. You can likely use whatever filament you'd like, but I'd recommend something with a high heat deflection, especially for the duct. Requires M3 and #4 screws to assemble.

All of the parts should be printed in the orientation they were provided. None of the overhangs exceed 55 degrees, so supports should not be used.

Check out my fork of Marlin 2.0.x with the required (and some personal preference) changes. **Please be sure to read all the changes before blindly cloning this repository. You don't have a fancy hardware lock like those Prusa Minis to prevent you from voiding your warranty :D**

A simple backpack concept for mounting a bltouch probe/PINDA and an air-pump for part-cooling to an E3D Hemera extruder. The bracket can be printed on FDM, but I recommend FormLabs High Temp Resin for the ducts.

There are 2 duct options, one for a standard v6 block and one for the larger volcano block.

I can't test these parts, unfortunately I don't have a Prusa. Maybe you do? They look like they should fit and I'm usually pretty good about these sorts of things. If they don't :shrugs:

Print these parts in their current orientation. Use 0.25mm layer height to take advantage of the incremental bridging. Do not use supports, none of the overhangs exceed 57 degrees and the longest bridge is 10mm.

Check out the following listing for a PINDA bracket and a air-pump duct: https://www.thingiverse.com/thing:4009736

Here are the plates for #ItsNotAnEnder to house the LCD panels. I'm sharing these for your reference, and have no intention of even checking this listing a second time.

The parts aren't oriented for easy printing, they're just how they were exported from Fusion360. If you can't figure out how to orient them to print easily, you probably shouldn't be building your own printer.

A heavily reinforced c-hub/steering block for the OpenRC Truggy.


Requires the following bearings/CVD Shaft:

- 1/4 x 3/8 x 1/8 inch Flanged Ball Bearings: https://www.amazon.com/gp/product/B00NKS71B0

- 1/4 x 5/8 x 10/51 inch Radial Ball Bearings: https://www.amazon.com/gp/product/B07DCRLDL5

I would definitely recommend printing these parts in CPE/PETG. CF CPE/PETG may come out stronger, but the additional friction from the part surface may put too much strain on the steering servo.

A universal drag chain bracket for an E3D Hemera. Easily swap from a v6 to a volcano block by simply changing out the duct and adding the bltouch-spacer.

The bracket should be printed with a durable material, and the ducts should be printed using a material with a high heat deflection.

A simple dog waste bag holder that can attach to a leash/key ring. I'd highly recommend printing this in 98A TPU.

Overhangs around curves are challenging with TPU. Print hot, slow, low layer height and with plenty of part cooling and you'll be fine.

Add some style to your #OpenRC Truggy with these custom side shields featuring the OpenRC Baseball Logo. Print in different colors or materials, or combine all the models to use with a single material.

Or, if you want to get crazy: print the main body in a durable material such as Fillamentum CPE HG100, print the infill with a stiff material like Proto-Pasta CF-HTPLA, then add some color to the inlaid logo.

Here's a very simple GoPro mount that I spent a few minutes designing. It is intentionally very tight on the camera bracket. Requires an M5 bolt/nut to hold camera in place. I recommend pre-applying double-sided mounting tape on the bottom so it can be mounted where you need it, when you need it.

Pretty self-explanatory: easily mount an E3D Hemera extruder to any MGN12 linear rail carriage. The top two holes for mounting the belt bracket should be tapped for M3 bolts.

It is somewhat complicated to install, and you will need access holes to secure the belt bracket.Start by securing the bracket to the carriage, then secure the Hemera to the bracket. Finally, secure the belt bracket to the extruder bracket.

Please notice the access that hole that was drilled in the 'x axis' bar. This is required to install the bracket without removing any parts.

Installation summary: https://twitter.com/brendonbuilds/status/1081643139406987264

All of the parts needed to upgrade a Robo3D R1+ to an E3D Titan Extruder. Using these parts the extruder will be able to handle any material you throw at it: from PLA, ABS, PETG, Vinyl, even TPU at speeds greater than 60mm/s (yes, including TPU with retractions enabled). The fan duct can easily be removed when printing parts that don't require cooling.

Use the recesses inside of the gantry to secure the cabling with zip ties. TPU performance is very specifically tied to the cap-tubes modification shown in the images. Using great care, it should be possible to drill out the filament guide and cut the PTFE such that the tubing goes right up to the gearing on both sides. It is important that the PTFE angle/position match the gearing as much as possible to ensure smooth flexible printing performance.

For the LCD holder, I recommend the following model: https://www.thingiverse.com/thing:87250

The filament tower was designed to be used with the Flexible, Adjustable spool holder: https://www.thingiverse.com/thing:3331712

Purchase all new rails from McMaster-Carr. They're worth every penny. I'd recommend upgrading the linear bearings as well, but that isn't nearly as important as the rails.

Required pieces:

8mm rails
(15x) #4 screws, 0.5"
(1x) #4 screw, 0.75"
(2x) M5 bolts, 10mm
(4x) M5 bolts w nuts, 14mm
(2x) M3 bolts w nuts, 12mm

Screw placement:

(8x - #4 - 0.5") - Gantry cover
(4x - #4 - 0.5") - Cold Break Fan
(2x - #4 - 0.5", 2x M3 bolts w nuts) - Adjustable belt tensioner
(1x - #4 - 0.5") - X-axis bump stop
(1x - #4 - 0.75") - Fan duct
(2x - M5 bolts) - 50mm blower fan
(4x - M5 bolts w nuts) - Filament tower

An easy to print raspberry pi wireless camera holder with recessed LED holes for 5mm white LEDs. I would highly recommend "diffusing" the LEDs by sanding them with 400 grit sandpaper before installation. Fits perfectly on a COTS gooseneck holder.

Before the details, how about a timelapse of one of these cameras being printed:

https://twitter.com/brendonbuilds/status/955457300524920832

Now, on to the build!

Parts:
Raspberry Pi Wireless
Raspberry Pi Camera

Gooseneck with clamp: http://amzn.to/2EYHpgw

8 - 5mm white LEDs
8 - 100 ohm resistors
8 - #2 0.25" screws
4 - #2 0.5" screws
4 - #2 0.75" screws
1 - M4 12mm bolt/nut
400 grit sandpaper (optional, but recommended)

Installation:

Mount the official raspberry pi camera to the front with #2 0.25" screws then install the LEDs/wiring. I'd recommend using a 3d pen to secure the LEDs in place. Mount the raspberry pi wireless module to the back with #2 0.25" screws. After testing all the wiring/connections (important!) join the front and back pieces with the #2 0.75" screws.

Place the M4 nut into the recess in the back anchor. I'd recommend using a 3d pen to secure the nut in place. Use the #2 0.5" screws to join the back anchor to the back of the camera assembly. Use the M4 bolt to create a rotating joint between the bracket and the back anchor.

Connect the bracket to the threaded end of the gooseneck. This connection is purposefully very tight and will cause the threads to really dig into the plastic.


Software:

I use the motion service as a webcam server to line up the shots before starting a timelapse. Here's a great writeup for setting up the webcam:

https://pimylifeup.com/raspberry-pi-webcam-server/

I use raspistill to capture the timelapse images:

https://www.raspberrypi.org/documentation/usage/camera/raspicam/timelapse.md

I then use avidemux to convert from .avi to .mp4 (mp4v2) (use hardware h264 for speed and twitter compatibility):
