3D Printed Rotary Vise for Electronics

[xrunner]

Anyone seen a PCB vise like this one - 3D printed or not? I ran across it on Thingiverse. I don't need the sponge holder on the bottom but otherwise I like the design. I'm going to print the parts and try it.

reminds me of  a mike stand with a few extra bits

Oh yea it does.

I'm going to get started on it today and see if I like it. It can't be any worse than the holders I already have.

There used to be things very similar to that, made of metal, in electronics shops in Hong Kong. I haven't seen one in quite a while, but I expect they are still around.

Got two parts printed.

More parts done. This is the shorter threaded rod. A longer one is available to print, but let's see how this goes for now.

I like the colour choices, to mimic a nice clean bolt and rust nuts.

I kept thinking this vise reminded me of something - I just realized what it was. 

[xrunner]

Well here's the final vise with the short king bolt. It's a good design and the parts fit together well. I really like this design and plan on using it a lot. Now I will print the longer king bolt and see how it fits.

xrunner, at what layer height did you print ?

xrunner, at what layer height did you print ?

The screws and nuts I used 0.15 mm, the base was at 0.2 mm

Note: Until about a year ago I used a 0.4 mm nozzle, but then switched to a 0.6 mm nozzle for faster printing speed. Unless you need meticulous detail as I did when doing a lot of model RR scenery, you can use a larger nozzle and it is barley noticeable quality difference.

Useful tool. I plan to make a second one

On the nozzle: I changed the diameter from 0.4 to 0.6 in the Prusa slicer just to check what would be the time saving, but print time decreased only one minute from 2h:09m. Maybe some other expert settings have to be changed ?

It depends on the file you are printing. For example, for the parts for this model, try the holder_bottom. I have 20 % infill, 0.2 mm layers (lots of other settings of course but we can't go on about all of that minutia).

For the 0.4 mm nozzle, Cura slicer gives 3 hours zero minutes.

For the 0.6 nozzle I get 2 hours 20 minutes.

That's a 40 minutes time savings, which is significant.

But for the kingbolt the times are 2 h 15 m for 0.4 nozzle as opposed to 2 h 11 m.

So you see how it goes, but overall the 0.6 nozzle is faster, how much depends on the movements and type of part design. I think longer nozzle movements where it is simply pouring out plastic and not having to retract is where it will start saving a lot of time. Stick with it! 

I printed the longer king bolt, 135 mm vs 100 mm. It came out great. Personally I don't see any need for the shorter one now.

Since I have all the files sliced I'm going to make a second one myself, but with different colors. Maybe holiday colors Hmmm ...

Yeah my initial try was on one of the 'kingbolt' files. But when I checked on 'bottom_holder' and look to more details it started to be interesting: the time saving is still low, 2 minutes only, but the used filament increased.



Later edit: The print time is shorter too. I can not tell if this is because of the printer or because of the print settings only.

Should be way more time savings than 2 minutes - way more. I'd have to look at a lot of other settings to find out why your slicer isn't giving you more time savings. Trust me, it really does cut down the time or I wouldn't have stayed with the 0.6 mm nozzle.

[rteodor]

After watching some videos I got the feeling that my old version of the slicer could be the problem. It does not change any speed settings after changing the nozzle diameter.
For now I don't want to update and experiment - its a tool that I just want it to work. But I will keep this in mind and get a 0.6 nozzle with the next filament order. Thanks for the tip.

Nice, but hot air will not be friends with this holder.
