3D printed parts NOW SORTED THANKS!

hi everyone, I’ve been posting up elsewhere regarding retro home hi fI, the components I have, came with pseudo rack handles like in this picture.Ā 

They are metal and finish off the components quite nicely. Does anyone have knowledge of how to get some of these printed for a ( potential) second set up I am looking to buy? Or does anyone actually do 3D printing that might be able to create some of these. Can the originals be scanned in somehow? What is the procedure, you can probably tell that I’m clueless about such things.Ā

EDIT; they are quite small items, 71mm longest side by 25mm wide.

Don’t know a great deal about 3D printing but for what you want to do why not fabricate a set. They don’t need to be exactly as the ones you have on your existing set, just a set of 8 matching ones. Side brackets in aluminium angle with chrome handles would do the job nicely.

I have had a look at something along those linesĀ Ā I really wanted something that matches the originals though? However, I suppose I could make enough for both systems? They will be next to each other on display, so need to match. I could then store the original rack handles away.Ā Ā Sounds like a plan if I don’t have any luck!Ā

Frightening price on an ended eBay listing.

Hi Barrie

I have a contact who does 3D printing. We have worked together to produce a couple of parts for the MX5 including a complex cog.

If you PM me some details I will ask him what he can do.

Guess you have already seen that ebay listing Roadie put up as used the pic.Ā Ā 

Barrie - as an ex rack user I can tell you these aren’t ā€˜rack handles’ but normal carry handles. That doesn’t answer your question, Sorry! - I have looked and considered 3d Printing myself, but at my age I’m whistling in the wind TBH. It’s also a big investment if anyone wants to do it professionally. Scanning alone is only half the problem, it’s the Pro software needed to convert a scanned image into digital language, so the printer can follow the program. - That’s also expensive, and a user would need a dedicated PC too I think.

Overall I reckon it’s a big investment, not forgetting learning more new tricks, and equipment usage and it appears, anything in limited quantity will turn out expensive too.

We’ll see what Rhino turns up -

I know Roadie, they are quite rare items though.

Thanks Rhino for your offer of assistance, appreciated, the deal I was on with fell through (that would have been required the handles) I’ve now just negotiated another system that has all the handles with the components so I’m good to go! Ā 

ā€œBarrie - as an ex rack user I can tell you these aren’t ā€˜rack handles’ but normal carry handlesā€

Thanks Gerry, that’s why I said ā€œpseudoā€ in my original post, they are purely cosmetic, an appearance item I suppose?

Put me out of my misery!  What was it!  I can’t open the link.  Thanks.

The picture I ā€œliftedā€ from the Internet was part of an eBay listing for a set of these handles. Just shy of Ā£100 posted!Ā

If these are cosmetic only they could be printed in nylon then sprayed with chrome paint.

An ex-colleague of mine printed up a prototype engine pulley adapter for my supercharged Suzuki 3 cylinder engine. It was a fairly complicated item. I drew it to 1:1 scale on graph paper. He transferred it to the 3D software on his laptop while we sat waiting for a couple of hours at work, then he took it home and delivered the finished item to me the following day. I used it to confirm it would work by fitting it to the engine. It did, so I was then confident enough to have it made in steel.

He’s not an engineer or a software professional, btw, just a clever chap.

Yes I was hoping for something like that as they are only cosmetic items. Rhino666 was steering me in that direction but then I happened upon some included with a hi fi that I managed to get.Ā 

Thanks anyway.

Barrie

We could have made you something ā€˜fit for purpose’ Barrie.

There are several types of filament available and I would suggest that these should be made from a carbon or preferably carbon reinforced nylon filament. The latter is probably as strong as carbon but much easier and more flexible to use and less tip heat required.

My contact with the 3D printer is highly intelligent and enthusiastic. He started the 3D printing to facilitate the manufacture of prohibitively expensive or impossible to find radio contolled helicopter parts. He has updated his printer at least once and the software several times over the last few years. The filaments are not cheap and everything has to be kept clean and dry.Ā 

No expert on the planning process for parts but it is more involved than simply scanning a part. We spent a lot of time discussing part improvements on original and Anthony had original parts to refer to. It is more of a graph paper and design drawing job than scanning I think.Ā  Ā  Ā  Ā Ā 

Thanks Rhino! I was thinking it would be a simple job tooĀ Ā I’ve been and collected the other mini system today ( including those elusive faux rack handlesĀ Ā There and back to and from High Wycombe to Leeds! Almost 400 miles and couldn’t quite do it on a tank, had to put Ā£10 in at Trowell services on the M1 on the way home Ā Went in the 5, weather not so good Ā in the North but surprisingly decent around High WycombeĀ Ā This set seems to be not as good functionality wise as the original one, cosmetically very good under 40 years of grime though Ā but has the very rare wooden cabinet/housing so was worth getting. Not given it a proper test yet. Mrs B has been highly critical of my second set up and can’t understand why I wanted the identical item again,Ā Ā there us method amidst all this madness though, which will be revealed in due course!
