Let me know if you need any instructions on this procedure.

I'm trying hard not to feel insulted...... I might not have mastered creating 3D objects but the slicer programme is fine (I've made enough mistakes to suss it out!).

Over the years I've realised that the initial design of something is not my strongpoint, but I'm very good at modifying/changing/adapting things once the hard work has been done (by someone else ). That's why I'm in awe at the relative ease with which you churn out these things!!! (And it's why I like thingiverse).

this is the only picture I can find

I will take some pics and make some measurements and get back to you. I can see a couple examples where a smaller cup would be a definite advantage.

I look forward to seeing them and helping if possible.

Sorry mate, I suspected you wouldn't have any probs with that and look forward to any help if needed in scaling in the slicer program for any who may request it. I do have slicer but got a bit disappointed when a couple of prints looked like they would work on the screen but did not come out as expected. Once I get used to a program and how it works I tend to stick with it often to some disadvantage. Question..... On the cap you printed does it clear the hook/shuttle stuff alright? It does on mine but I run my filament at 1.74mm and hot in order to extrude a bit heavy and this gives excellent bonding together but some times things come out a bit on the larger side.

I haven't actually tried it working so I'll have a look tomorrow.

Nice! I heard you can smooth the surface of the ABS plastic with aceton, does it work 

[RockyAussie]

Hi Tor, long time no see. I myself have only tried working with the ABS a couple of times and did not get great results. I did try the acetone on it and it seemed to work some. Mostly I use this pla+ which claims to be stronger than the abs and a few other alternatives. So far I can't fault it.

I forgot to get back to you about the cap, sorry about that. I ran the machine, no funny sounds or signs of scraping so I guess it fits ok.

WOW that was quick. Looks better than my yellow coloured ones. I am hoping that a few of the other members that have clones of these machines will try them out for fitting. I would like to have a list of the various machines clones etc that it will fit onto to advise everyone. Also if there are any negatives as to where the cap may be improved. For 27 cents of filament electricity included. its not that big a risk really. So far mine have tested in use well and I will do a few more  little changes once I am confident it will fit a wide range of other clones as well. I am thinking of putting this thread into the sewing machine section in order to get some more feedback. Thanks for the feed back.

I have printed presser feet and needle plates for my Campbell Randall for parts they don't make anymore.  They don't last as long as steel but when they wear out I just print another.

I've been thinking about doing a little bit of that to make up some for special jobs like leather covered rope handles with a shaped needle plate and feet etc. I think the feet would need to be bulked up in areas compared to steel but I doubt that would create too big an issue. Zipper guides should be another interesting one to look into.

I didn't have to bulk anything up but if you have room it wouldn't hurt.  

I'm looking for a narrow arm cylinder machine.  Any thoughts?
