I mostly use E3D or 3dfilaprint. I have a load of Rigid Ink PLA left that I will work through and then I'll have to look for another brand, probably Prusa as that performs well on my machines.
Rigid Ink getting out of the market is a shame as I always found their PLA to be reliable. Faberdashery also appear to have ceased trading, which is a shame as they offered some nice shades of PLA (at a price...).

I've been mostly buying from https://www.3dqf.co.uk/pla-product as I like the idea of supporting a guy starting up in the UK.
I'm currently working my way through a 12pack of AIO Robotics PLA I got from amazon.
they come in .5kg spools instead of the normal 1kg. They are also lighter in colour than on the main picture on the product page although there is a second picture that shows the proper colours, so you don't get a dark blue or green.
I've also got a roll of GEEETECH Wood filament.

I have a Prusa MK3/S and a bit of a bastardised Creality CR10 running a Duet2 Wifi board and an E3D hotend.
The prusa gets the most use as it is pretty reliable once you have it dialled it. My current project is to design and print 4 adapter plates to make my new low power LED spotlights fit in the recesses that some old GU10 spots lived in. I'm using Nylon, which has a melt point higher than the LEDs can get to.
BTW, those of you using Fusion360 might notice that the personal license is going to be hindered a small bit. Autodesk have obviously gotten pissed off with people, particularly youtubers, making money off their free license, as they specifically invite them to 'discuss opportunities' with them.

Hello 3D Printers of PH...
Please excuse the following vague and uneducated ramblings but I know little of 3D printing, particularly the design portion.
I got a GoPro for Christmas and would like to mount it to the tail unit of my motorcycle.
I've searched the 'off the shelf' offerings and I can't seem to find the type of mount I had envisioned, so I wondered if I could have one 3D printed...and then I wondered if someone on here might be able to 3D print something in exchange for Beer Tokens?
Essentially, I'd like an 'S' curved arm as per the below link however, I'd like to be able to use the GoPro-style quick-release type attachment at the base (so I can just leave the curved stick-on mount on the tail unit) and have the thumb-screw fitting at the top of the arm, to mount the camera.
https://www.thingiverse.com/thing:1224316
Hopefully those of you that have a GoPro and/or have made bits and pieces for one will know what I'm trying to say and for everyone else, apologies for my ramblings.
Is what I'm after reasonable or should I just suck it up and make do with what's currently available from eBay/Amazon?

I presume you mean this sort of mount at the base of the design you shared?

Combining two existing designs is quite easy, although you might be left with something that is a bit tricky to print. It might need to be printed in a couple of pieces that glue together. Material choice is important for action camera mounts, the material that’s easiest to print (PLA) isn’t really strong enough. I’ve printed a few GoPro bits with PETG and they seem to be holding up ok.

Thanks for the offer Spragnut and for interpreting my garbled post Accelebrate.
You’re right, I’d like the orange spring-clip base bit to be the bottom of the ‘S’ arm and at the top I’d like the bit that receives the other bit that you tighten with the screw thing...
Do you think a job at GoPro or some hi-tech design house beckons for me
ETA: I'm aiming for this sort of camera positioning/height etc. with the GoPro (approx. 75mm height).

Yeah, I'm dubious about PLA for GoPro mounts, I haven't had much success in the past. I have some PETG, although I'm getting mixed results from that at the moment, I suspect because my printer is in my garage and it's currently a bit chilly! If someone is setup for printing ABS and wants to give it a go here's the STL...

That said, the quick release I used was supposedly designed for PLA. I did a 100% infill print and it seems to flex without snapping, I'll try it on sticky mount tonight. It came out reasonably well, apart from a bit of goofiness where the supports attached:

Nicely done! That's a great looking part. Tinkercad is great for quick stuff like that, isn't it?
I'm starting to move on from printing random tat from Thingiverse, to designing and printing my own parts to solve actual problems.
Currently, I'm discovering that printing accurate holes is quite tricky, and so threaded things don't fit together well.
This was helpful in understanding why:
http://www.deltarap.org/printing-undersized-holes
I can just about do nuts and bolts now, where it doesn't matter if you scale the entire nut up a couple of % to make it fit over the bolt (just on X and Y, not Z so the thread pitch doesn't change), but if I had a complex part with threaded bits in it, or even just accurate holes, I wouldn't be able to scale the whole part in the slicer to make the holes work.
Has anyone been through this?
Do I wrestle with getting my print settings as accurate as possible? I feel like this is doomed from the start, as fundamentally 3D printed Cartesian X-Y movements are only ever going to be approximations of round holes.
Do I start building in tolerances in Fusion360 at the design stage? I feel like this is wrong too, as the model should be accurate and reusable for any sort of production technique. If any adjustment for FDM is needed, it should be the job of the slicer to tweak the model, methinks.
So, do any slicers have any sort of holes and threads settings? I'm aware of horizontal expansion in Cura, but it's a bit of a sledgehammer and affects th entire model unless you start masking bits of the model, which I haven't got to grips with yet. I feel like there should be a holes and threads setting somewhere, but Cura doens't have it. Has anyone got Simplify3D experience of this issue?

Amazing! As someone who's personal computer ownership went Amiga 500+, Gameboy, PS2 <End> it's still like magic to me how you can go from awful description to actual real thing exactly as envisioned, despite the hours of clips I watch of 3D printing, CNC machining, water jet cutting etc. https://www.dropbox.com/s/y8k20a90d2x6pec/GoPro%20...

Remembered that I had a roll of https://www.amazon.co.uk/ZIRO-Printer-Filament-Car...
Printed nicely, the quick release seems to flex in and out of a GoPro mount just fine. However the camera mounts at the top seem a bit fragile, I snapped one of them whilst removing the supports.
