I love that style of knurling, it’s different than what most so do for 3d printed parts. Thank you Jerry, I appreciate your kind words!

Dean Markel Posted February 19 Report Share Posted February 19 Thanks, Nikos! I had a friend a school with tint one of these out for me and it turned out great. The threads were much cleaner and stronger than I expected. Quote Link to comment Share on other sites More sharing options...

I had a friend a school with tint one of these out for me and it turned out great. The threads were much cleaner and stronger than I expected. You are welcome Dean! Yes I wouldn't really worry about the threads. If you were to reach their strength limit, you'd probably have applied way too much pressure anyway and would have definitely marked both the ribs and the linings pretty significantly. However if you or anyone who prints them find a problem with the threads, please let me know and I will change them and make them a bit thicker and less in number.

martina hawe Posted February 19 Report Share Posted February 19 Hallo Nikos, very nice clamps! There is something similar used for medical purposes. Their flat cheeks can be shaped with a chisel create some round ones for the c-bouts, it´s a bit laborious but ok. (I woulnd´t want to make a set for Cello) Quote Link to comment Share on other sites More sharing options...

(I woulnd´t want to make a set for Cello) Yes I am aware of those, I've also seen some similiar ones for aquariums I believe. I'd honestly be impressed if they are any strong. This hollow region on the back of the body is probably a weak point and considering they are made out of plastic (?) wouldn't they bend too much when clamping the linings? Are they actually made of plastic or is it some other material? Quote Link to comment Share on other sites More sharing options...
David Burgess Posted February 19 Report Share Posted February 19 Nikos, this is the sort of thing I was thinking of: (Note, the spring could be closer to the clamping surfaces to exert more pressure. Springs can be bent with pliers to apply more pressure. Might be easier to make by modifying existing clothes pins than to 3D print and assemble) Quote Link to comment Share on other sites More sharing options...

That's a great idea actually. Thanks! Quote Link to comment Share on other sites More sharing options...
Nikos Matsablokos Posted February 19 Author Report Share Posted February 19 @David Burgess Here's the design, not completely ready yet but the general idea is here. I believe I can print it. The photos below are a cross section and a normal view of the part of the clamp that will have the moving jaw. Quote Link to comment Share on other sites More sharing options...
David Burgess Posted February 19 Report Share Posted February 19 Neat! Looks like it would snap together, with no need for drilling or pinning. I don't think you'd need a slot for the forward part of the spring. That might make the beam a little stronger, and also give more spring tension.

I don't think you'd need a slot for the forward part of the spring. That might make the beam a little stronger, and also give more spring tension. Yes it doesn't require drilling. As you've explained it snaps together, that's why the moving jaw has an opening on top. I've already made the body thicker than a usual clothespin so it will be stronger anyway, even with the recess for the spring. But I will give it a try without the recess I am actually printing in right now. I expecting I might have to move the pivot point of the jaw further towards the end of the clamp. Because if you want to clamp beveled linings, the pivot point should be towards the thinnest part of the lining so that the jaw, closes properly. I'll give it a test though. Soon I will post the follow up of the 3d printing results... Quote Link to comment Share on other sites More sharing options...

Gary M Posted February 19 Report Share Posted February 19 Love the 3D printing idea. I'll give that a try if he makes the .stl file available. I have used these for attaching Ukulele linings. Each one may not be as strong but they are so cheap you can use lots and lots of them. They have a nice wide mouth. I stole them from my wife's sewing studio. Sewers use them instead of pins for some things. Quote Link to comment Share on other sites More sharing options...

That one is already in the queue behind some student jobs running this weekend. Thank you so much for the "Gift". Can't wait to try it. The other design is also interesting. I'd give that a try as well. Quote Link to comment Share on other sites More sharing options...

I did print it and the tolerances where too tight (for a 3d printer to handle). It worked though, I just need to make the jaw shorter. I will upload this stl as well as soon as I am done probably by Monday, maybe sooner. Hope you find them useful Quote Link to comment Share on other sites More sharing options...

I'm not sure if your post was particulary ment to this thread, but I'll answer as such. 3D printing is a way to quickly put drawings and ideas to practical objects. Its potential is because it is digitized. It enables that the data about the print can be put into prototypes instantly, for ex. over the Internet. It is not for serial production, there are far more efficient ways for that. I own an accounting agency having seen several businesses gone bankruptcy having failed to understand this.

You seem to have too much free time, why don't you open a new thread discussing your opinions about 3d printing and all the economical disasters it may cause. This is not the thread for that. I created this thread to help anyone who might have a 3d printer to help him make something useful for what we do. What you are writing not only isn't helpful but has nothing to do with the thread as well. Start another thread for that, this is not the one.

Nikos Matsablokos Posted February 20 Author Report Share Posted February 20 @David Burgess I managed to 3d print it. Changed it a bit because it didn't work that great the first time. Still there are minor modifications i'll have to make. But it works great. Not only can it clamp parallel and apply even pressure over the whole lining it can even clamp pre beveled linings. I also made it so one can print only the moving jaw part and use a normal chopped off clothespin for the other. Thanks for the idea Here's how it turned out. Edit. Also radiused the jaw, so the corners don't dig in Quote Link to comment Share on other sites More sharing options...

I don't have a printer, but I'd definitely buy a set of these. I will upload the STL tomorrow (3d printing file) after I make some small improvements. You'll most definitely have some 3d printing service shop near you. There are pretty much in every city lots of them. You can send them the STL file and they will print it for you and charge you the service of course. I don't think it will be too expensive and they'll probably do a great job printing them since they tend to have very high quality machines. Much better than the home user me and many others use Quote Link to comment Share on other sites More sharing options...
