Re: Question for IBM Selectric enthusiasts about keys

I made something like this for a beamspring. I am actually finalizing the design as I find time but check this out. The first link has a short video to show its actuation. https://www.instagram.com/p/Bpvq7QpF1gf/?utm_source=ig_share_sheet&igshid=12e6b0hlvz0k8 https://www.instagram.com/p/Bpp38IZl94B/...

I was not expecting it to be that low... That is fantastic! I would recommend talking to a powdercoater and see what impacts the materials have on the powdercoat durability on different materials. I don't have much experience in that other than having it done for me on some projects but it may be wo...

Excellent news. I figured there would be a point where they would just tear off the base. PLA does not have excellent characteristics in tension in the Z axis. An SLS printed part would be much more isotropic and made of nylon which is a better performing polymer by a large margin. I am going to pic...

Re: IBM Beam Spring - MX mount

Updated file sent. I reduced the stem diameter and elongated the return spring end by 1mm. I'm glad that this is not only an adaptation for new cap options, but an improvement to the feel of the keystroke. I was thinking it would be wise to thicken that return area as well just as added insurance of...

New design that lowered the cap height 2mm. I cant go any more than that from what I can tell, I may be able to squeeze out a little more if I re design the part. The sizes have been moved to the nominal sizes you provided. The challenges with FDM printing is that with small features, tolerances are...

I don't own one of these boards sadly. This is certainly a difficult one to do unless you know a fabricator though, most job shops wont want to touch this for a reasonable cost to you as you have found. I know the aesthetics of having a matching powdercoat is important, but is there any want for a r...

The model is designed at 3.8 and at the excrescence 4.8, so from the printer there is some variance. I figured this is going to be the case, we can tune in the design to your printer to start with though so we can best evaluate the design and move from there. I will adjust the design accordingly to ...

Re: IBM Beam Spring - MX mount

I came across this for your foam issue http://imgur.com/a/IqNlH Relatively time consuming and laborous it seems. But if you have the tools already its not too bad and I am guessing many beamspring owners are ok with a labor of love. This may be something that could be produced with a laser cutter or...

Re: IBM Beam Spring - MX mount

Excellent! It's great to see you using them. Are all of the MX caps the new version or are some of them the earlier one you were testing? On the barrel fit issue, I undersized the stem going into the barrel to ensure it would fit, but apparently too much, that is easily addressable. The height can b...

Hmmm.... Ya know, there may be but I would need to do some closer investigation on the design flaws of the layout. If this is a want in the community I could look into picking up a single switch and try things out from there. To be clear, you are talking about keeping your existing caps, stems, etc....

Interesting. I wish I had one of these to play with. I think its plausible to build a stabilizer for this, if I am not mistaken it could be possible to print this adapter piece with a built in stabilizer for those wider caps. That would take a little messing around but I could see it being possible....

That is AWESOME!!! I have used a beamspring many moons ago and wish I could get my hands on one. By the way the pictures of the barrel are perfect. I thought that was how they were setup, but wanted to make sure I wasnt missing something. Side questions, what issues did the modifier keys have? Also ...

Mostly I need the inside diameter of white part, the rest I can work around. https://deskthority.net/w/images/2/22/Beamspring-top.jpeg Can you take a picture of the white part with the metal insert not in there as well? If possible get the picture from a top view so I can get a better sense of the p...

Ok so here is my latest setup. https://imgur.com/a/S5j4QT0 This takes into account the shorter 21 mm size, and a bunch of other improvements that I wont know if they work til someone can test it. If you are up for printing this, PM me and I can send you the file. This version is somewhat hard to pri...

So I have a new model I am working on but need some details on dimensions. Do you happen to have a dial caliper? If not I can make a general model and we can go from there. I am working off of pictures online only right now so its a little difficult to be precise. Worst case senario I can grab one o...

Hello everyone, I saw this post and it interested me because I kind of really enjoy solving these little problems. I took the designs here and modified it for an easier way to tolerance around the Cherry MX cap. Printing that cross accurately and with appropriate tolerance can be difficult unless yo...
