Nắp Che Đầu In Centauri Carbon Bản Dùng Vít - Another Centauri Carbon Toolhead Cover

This toolhead cover favours strength and low weight over easy access and magnets.
If you install the constellation extruder you won't need to access the hotend often since you can simply change the nozzle from the bottom.  It also doesn't cover the toolhead LED pads

The fanshroud might also be compatible with other hotend mods

One of the lightest toolheads: 34g of printed parts, 30g fan and 2g of screws for 62g in total. compared to 95g of the gamma toolhead, 99g SE3D and over 120g for the stock toolhead. As of now (from my knowledge) the lightest toolhead, in part due to minimal hardware.

Big thanks to Robert Samples for making the gamma toolhead step available and providing the idea of the replacable fan mounts!

BOM

• 2 M3x6 BHCS

• 1 M3x12 FHCS

• 4 countersunk screws from the stock cowling (M3x6mm FHCS)

Print settings

• 0.12 mm layer height

• 2 walls

• Print as oriented

• no supports

• Print out of PETG, ASA or better

• Precise wall

• Precise z height

• Ensure vertical shell thickness All

• Bottom/Top shell thickness = 1mm

• 10% gyroid infill (or other just has to be low density)

• set the honeycomb modifier part to be a modifier or remove it

Installation

1. Remove elephants foot from the hexagonal holes if necessary, and remove the included supports that are beige colour in the picture below. For the top left edge you will need to carefully cut it with a knife.

2. Cut the threads in the pegs with a M3 screw while making sure to not go too far, to make this easier you can hold it with a towel or similar.

3. Insert the fan into the cowling.

4. Insert the pegs into the cowling and fan, this is a tight fit and might require a bit of sanding or scraping to get working.

5. screw in the fan with 2 M3x6mm BHCS, DO NOT OVERTIGHTEN IT.  The pegs and printed threads are quite weak so it doesn't take much. If you break one you can just replace it.

6. Attach the cowling to the toolhead using the 4 M3x6mm FHCS, don't forget to plug in the fan.

7. Attach the back bumper to the toolhead using the M3x12mm FHCS.

8. Let it rip
