3D Printing

Cheers, will hit you up on that. Problem is the Chinese Brompton I got for my gf, is out to tolerance and therefore needs a larger sleeve to accommodate the seat tube from slipping.

Never heard of this, will check them out now.

Don't know if this is a piece of string question but I'd like to try scanning, altering and 3d printing additional brake fairings on my Cervelo. They only come as a front fairing which I already have but it would be fun to mod slightly to work on the rear too.

Is scanning the original really ££?

Anyone creating their own stl files here? Keen to get some tips on creating a pretty straightforward file from an image. I'm creating a print of all the tracks I've won at this year in the sim rig. Managed to find a guy who's created over 200 1:10000 scale race track files but there are four track variations that aren't in that file set:

1. Okayama Int (short variation)
   
2. Summit Point (Jefferson circuit)
   
3. Outlton Park (Fosters variation)
   
4. Oran Park (South)
   
   

There are plenty of circuit maps available online (example below). What would be the workflow to get them into a printable file and scale them to the other circuits?

I think this should be straightforward...

My numpty way of doing it would be take the PNG, convert to SVG (online), that can then be imported to TinkerCAD, you can then set heights etc. and trim

Something like this

• Swanky Juttuli-Migelo.stl

Find someone with the latest iphone with Lidar in it. Scan using that, then spent a day scaling and verifying the critical dimms. A lot faster/cheaper than commercial 3d scanning services.

Got a bunch of '3dQF' filament last year. Impressed with it, most PLA once opened even if kept in a box full of desiccant seems to give weird issues (popping sounds when extruding which mostly just leaves a bobble, but sometimes ruins the print as it skips a layer), this stuff in same situation has been happily printing away this whole time. Only £13-16/kg too. Ordered a reasonable amount and got a few free partial rolls chucked in

interesting, I just got some cheap stuff off Amazon, and it is awful, struggles with adhesion and getting loads of stringing. Annoyingly I have 3 rolls of the stuff to get through, I have had to significantly increase my heat to get it to flow a bit better. Will bookmark 3dQF for next round of purchase.

Would say on principle I avoid anything on Amazon. But have found in some products, the sellers on there sell seconds or actual faulty stuff, but at full retail, and then good luck trying to return or 'prove' thats its faulty.
Once bought a supposedly genuine Mikuni Japanese digital caliper, the price was the same as from anywhere else £105, had many reviews, but just needed one very quickly and only place that defo had one.
yeah it was fake. Couldn't prove it, could only return it, so some more poor buggers will end up with fake or junk goods.

Thanks, will report back if I manage to produce something road-worthy.

Have returned the Amazon stuff, and ordered some from 3DQF, so will report back.

Have also flashed new firmware to the printer, gives much more options.

I’ve used PLA from 3dprintz for a few years now, have never had a bad roll.

Have you tried shimming it with e.g. aluminium drinks can? Not sure 3D printing will be tough enough for this application..

Anyone got any idea why my prints are getting this minor imperfections?
Printed on a Q5, using Foxy, everything else st
Sliced using Cura.
Heat 195.
Bed heat 70
Layer height 0.2
Retraction 6.5
Retraction speed 25

First layer adheres fine (wasn’t before hence the bed temp higher), and overall print is fine, just lots of wispy hairs and the occasional area of what looks like layers not adhering.

One thing to note this is a scaled up STL from a smaller design, scaled roughly double in Cura, not sure if this could be a cause, but I do get lots of wispy bits on normal STLs too.

Any ideas?

And shamelessly copied from @MrE in the sewing thread, a bar bag end cap.

I'll be interested to see how that works - my first version was just a perforated rim which was successful in arranging uniform hand stitching in 3D, but I struggled with fabric tension - the ends became Pringle shaped, with additional wrinkles.
The second version (in the sewing thread) has a filled centre which gives a convenient surface for contact adhesive to hold the fabric flat while everything is pulled tight.
I did contemplate a central captive nut to fit a light mount - perhaps in the next version...

Here you go

I think this is pretty good, it's not super tight like a drum. The reason I didn't do a full disc was impatience. 3d printing is slow....

Looking good! Pre-cut holes in the fabric?

I've seen you have (or have use of?) a laser - it reminds me of doing leatherwork with KS4 students, using laser cut parts including the holes. CAD spacing (and avoiding the need for a class set of awls) allowed them to make some very convincing products: tight lacing gave the impression of machine stitching, but the smell of burning leather is still with me even after 12 years of retirement.

access to - there's one at my local makerspace

I've used it to cut leather for various projects, works really well, and yes, absolutely stinks. I wash the patterns in warm water and dry them outside afterwards.

@Soul
How are you getting on with the FLsun? done any upgrades?

Couple of recent projects.

An UNO card holder and playing tray, ready to use on holiday.

And personalised dividers for my brother, to store fiddly auto electric bits.

Good. Took a little while to get a good dial in for the magnetic plate but it's printing really well at the moment.

Printed out a load of cable clips for my Festool vac / power lead recently and it's currently printing three battery clips and two tool clips for my tool wall.

No upgrades other than the magnetic mat. Need to print some sort of accessories holder though as it's all just laying around the place.

^ Ignore the smushed outline before the print, I'd fucked up the Z height but fixed it before it started printing.

edit: what layer height is that? looks nice and low...!

Nice. Yes, I found the magnetic plate works really well when fully dialed in.

There are a few nice tool holders that use the screws on top, I particularly like the one that just holds the auto level.

I found that after a fair bit of use, my extruder was getting pretty noisy, so have just switched to an all metal micro-swiss one, its much smoother and quieter. Also have printed some better fan ducts, but have yet to install them yet.

Some prototypes for the workshop…

10mm festool dominos with a festool D27 hose clip for a temp / perm hose holder for the edge of workbenches etc.

Will be testing and finalising when I re-do my workshop next week.
