Why not flush mount the lower rod-holders? You have them slide in with the nut, but you could've made it a tiny bit shorter and then recessed it so it fit in nicely... Also, why not recess the nuts / etc.. for the other parts?

Otherwise it looks like a decent copy of the Weller PCB Holder - I'll probably make this as soon as I get a printer.

Hi,

Is there any chance for posting the step files?
I would like to make some modifications and optimize it for my printer. Also would like to remove the groves so, no support is needed.
And would like to reduce the thickness as well. So, quite a few modifications. It would be ideal if step files are available.

Thank you.

P.S. Great design by the way.

I like the idea how you designed the insertable nut-holder plugs. I'll steal that shamelessly for some projects of my own... ;)

I really like to hear that! I hope to see some of the projects in which you have used this idea.
Thanks for your comment Chattermak

You can buy a clamp just like this one for $12 on Amazon. I like the use of the rods in braincodec's design, but for the cost of the parts it may be a wash to buy the Amazon version.

wow I didnt know it was that big
I just found these today too :-)

Hi Joinc, thanks for comment and for the link I like the rods system too and maybe the more important thing about my design is on the right hand mechanism.

Yes, obiously is possible to buy a clamp, a very cheap clamp, but the model I designed is comparable to this one:

http://www.weller-toolsus.com/weller-t0051502699-esf-120-esd-antist-pcb-holder.html

and my design (clamp mechanims) is better in my opinion and as you can see the price is about 61,6' USD$ more tax & shipping.

Moreover I made mine with recycled parts mainly so the price for me was not a problem and the better thing I'am maker!! so I prefer to do my own tools if it is possible, you can modify, adapt to your needed, etc.

In any case the clamp you show is really cheap and for many people will be enough.

(more like) where do you find the rods ?

Hi phil123456! In my case the rods are from an unused inkjet printer (Recycling!) but you can found 8mm rods in many sites on internet:

Thanks for comment.

Can you put here some links where i found those springs.
I can't find my local store.

For example, you can buy the big one here: https://www.aliexpress.com/store/product/Custom-small-diameter-coil-metal-springs-compression-springs-1-5-16-45mm-MHS-S6/739321_32781054741.html?spm=2114.12010612.0.0.QMbt7N

as you can see it has an outer diameter of 16mm, wire diameter of 1.5mm and a free length of 45mm, maybe you must cut a little so we need 36mm of length aprox.

Also you can found more springs from the same seller here:

https://www.aliexpress.com/store/group/Compression-springs/739321_506988147.html?spm=2114.10010108.100008.1.bRttSV

and here you have a list of other sellers:

http://www.steelmefobo.com/muelles-tiras-metro-surtido-mixto.html
http://www.acxesspring.com/wire-springs-inner-diameter.html

You must keep in mind that it is not 100% obligatory to use the same measures, you have certain margins.

For example, the big spring for the right hand is the same you can found in this fitness device: https://es.wallapop.com/item/tensores-de-manos-13769569

You also can found the springs on an old inkjet printer, etc.

You can also find this type of springs (the big one to the right hand) in many shops in 1 meter strips.. You will have to cut it to the necessary measure.

Please, let me know if you finally get the springs, good luck!

Where did you find those springs?

Hi junnu78! I found the springs in a local shop but in E-Bay there is a lot.

If you have any problem to find that, please say to me.

If you make this thing please share with us! Thanks!

Last month I ordered some boards from PCBGOGO and I was amazed about the quality and service with competitive price.
You could use them if you have boards to make.

Too bad... It doesn't print on a printrbot simple metal because the legs are too large :-(

takes 2 seconds to split anything in any 3D software editor

Hi sinclairfr, but the PCB Holder is a very good thing. Maybe you want to say your printer don't have the needed dimensions, sorry for that. Leg dimensions are about 15,5cm x 16,5cm so in many printers the bed dimensions are about 20cmx20cmx20cm o maybe more.

If you want you could split the leg and print in two parts which you could assembly with some type of nuts.

Or if you want you can apply a little SCALE before you print this thing (Warning! Scale all the parts by the same factor)

You have many options.

Thanks extera

You can see the video tutorials I uploaded on mounting the PCBHolder.

When I get some time i'll do a BOM, stay tuned.

Nice design!

Can you post a BOM? It' s hard to see the size from the pictures!

Hello

I would be awesome if you would list what screws and road you used, and the size of the springs and where you use the springs
