[Tips] 3D printing the headset frame

[Ybalrid]

Hi guys!

So, I suppose a lot of people are going to throw the files on these repository into a number of different desktop FDM 3D printers.

I would be curious to see what configurations and settings we are using. I've been attempting to printing the "FDM Optimized" Optics bracket since yesterday.

I finally resulted into throwing the file into MeshMixer and adding a bunch of support around the frame that should hold the reflectors.

I'm currently printing this on RED Prima Value PLA with the following settings on a Dagoma Discovery 200 3D printer (little machine made by a french startup a few years ago. Dirt cheap but not really reliable I'm affraid 😅 ) :

• Temp 210°C
• 0.2mm layer height
• Raft on
• Supports off (added by hand in meshmixer
• Infill 100% (it's not that much plastic anyway)
• printing speed 80mm/sec

I've made several attempts at printing this between yesterday and this afternoon, but this one looks promising.

If it 3D prints nicely, I'll share the modified STL in a pull request :wink:

I'd love to get that STL, for use on the Dremel 3D20 at my office

I just have to see if the lower (upper here, since it's reversed) part prints fine as is. The overhangs aren't that big so I'm confident.

My print will end in 40 minutes from now ;-)

I saw this bracket on twitter, great work @Ybalrid . Big time saving to not have all that support material. You may be having a bit of over-extrusion and printing too hot judging from surface finish, maybe this caused your print failures? I had a lot of print failures from the support material becoming loose from banging into extruder. This guide helped me a lot:

The print posted on Twitter turned out good acutually, the lighting on the picture was a bit harsh
