Blank Keycap (R1, 1.25x)
RaVNzCRoFT @coldblackkey I'm sorry the product you received was not to your satisfaction. Small tolerances can be a problem with 3d printed parts, especially when considering different materials like plastic and metal. Have you tried taking any steps to remove some material from inside the stem area? It probably won't take much for the keycap to fit your switch properly.

RaVNzCRoFT @fbeb2f3 No, the Sidewinder x4 is not a mechanical keyboard so this keycap would not work with it. I do not have the metal bar. sells them for mechanical keyboards but I do not know what type of stabilizer bar your Sidewinder uses.

Blank Spacebar Keycap (5.5x)
RaVNzCRoFT @SigBin Thanks for your comment. I'm sorry you were not 100% satisfied with your purchase. These keycaps are 3D printed. As with any additive manufacturing process, the finished product may have a rough surface finish with visible ridges. This is based on the resolution of the 3D printer, and Shape ways has some of the most advanced 3D printers in the industry. Visible ridges is one disadvantage of 3D printing...of course, one of the biggest advantages is it gives you the ability to create anything you want -- including rare 5.5x space bars like this one.
RaVNzCRoFT @baesex Thanks for your question. I can't really say which key sets it will or will not match because there are so many sets out there and no way of knowing precisely which color a particular set is. However, most white keys seem to be pretty close in color. Lots of people have purchased my white keys to go with white keysets and I have not heard any complaints about the color not matching.
RaVNzCRoFT @kmenter7 Thank you for your interest in my products! :D
RaVNzCRoFT @kmenter7 Here are a few pictures of a purple 6.25x spacebar:,,, Let me know if there anything else I can do to help!
RaVNzCRoFT @Raishiwi By stabilizer I assume you mean the little white plastic pieces that you put into the spacebar stem holes? If so, no, this product does not come with those. You can buy them separately from or

RaVNzCRoFT @ranhiru I'm afraid not. SA profile keycaps are made by Signature Plastics, and I don't have any of their keys to measure. You can try contacting them, they can probably make you a custom space bar.
RaVNzCRoFT @ief_mathias Hi there -- I'm very sorry to hear that you were not 100% happy with the product you received. I have spent many hours working on all of my keycap models to ensure they are of the best possible quality, and I know Shapeways invests countless resources toward developing their 3D printing technologies to deliver a product that satisfies their customers. Unfortunately, 3D printing is a relatively new process and there are still some areas that can be improved. From what I can tell, your order was placed on December 16 and you chose Strong White & Flexible material , as you have said. In my experience, the White Strong & Flexible POLISHED option is more suitable for a keycap than the unpolished version you ordered. That's not to say one is inherently better than the other. But I personally prefer the polished version because it is not nearly as rough as you described yet actually does have a nice grainy feel. I would be delighted if you decided to give me another chance and order a polished version instead -- perhaps a different color this time since you've said you don't like how Shapeways' white color doesn't quite match the rest of your keyboard. But of course that is your choice and at this point I couldn't possibly blame you for saying no. Here is a picture of a S&F Polished space bar; you will probably notice it looks quite a bit smoother than the one you received: I know that it can be difficult to find replacement space bars, especially ones that are a custom size like this 6.5x--that's one of the main factors that motivated me to create these custom space bars in the first place! For this reason, I will offer some advice in hopes of making the space bar you purchased as useful to you as possible. You mentioned it fits loosely on your switch stems; this is actually by design, since there are some rather large manufacturing tolerances involved with 3D printing. The keycap is pretty much useless if the holes are too small, so I intentionally made the holes a bit bigger. In some cases the manufacturing tolerances stack up perfectly and the key ends up fitting great. But in your case, the holes ended up being a little too big and the key is loose. Did you know there is a simple solution for making a loose key fit the switches better? All it takes is a few small pieces of scotch tape, like so: Over the months I've had a handful of customers contact me, initially disappointed that their key was loose, but after teaching them that trick they were all thrilled with how effectively it fixed their problem. I hope you find it useful as well. I try to be very transparent with all of my customers--the last thing I would want to do is deceive you. Please let me know if there's anything else I can do to help. Again, I'm truly sorry this product didn't exceed your every expectation. Happy clacking, --RaVNzCRoFT

Blank Keycap (R3, 1x1)
RaVNzCRoFT @ataiello I'm very sorry to hear about your keycaps not fitting. The stem holes on all my keys are actually quite a bit larger than a Cherry MX switch by design, because of course it's much easier to make a loose keycap fit properly than it is to loosen a keycap that's too tight. When printed in plastic, all of my keys either fit properly or can be made to fit properly with a simple solution (a small piece of scotch tape: However, as you have noted here, in this case for metal it seems there is still residue in the stem hole and the hole itself may even be too small (although I can't tell from the picture). Unfortunately, my best advice to you is to take the most obvious next step--continue trying to scrape out the plastic residue with a sharp pick and, if necessary, try to file down the + hole until the keys fit properly. An X-ACTO knife, pick tool, or perhaps a very small drill bit may be good for removing the residue and opening up the stem hole. Be careful about trying to install the key if it is too tight, because there is a chance the switch will be pulled from its housing if you try to remove the keycap. I'm afraid there's not much I can do for you myself, as I am simply the designer, not the manufacturer. I do not handle payment, shipping, warranty, etc. You can certainly contact Shapeways' customer service and claim you received a defective product since these keycaps are known to work when printed in other materials. In fact, I've even had some customers who ordered more than one of the same keycap in metal claim that some fit and others didn't, which is a clear indication that Shapeways has some inconsistency in their products. But they will probably try to play the caveat emptor card, since 3D printing is not an exact science. I hope my response has been at least somewhat informative/helpful and sufficiently prompt. Please let me know if you still have questions or concerns, and I wish you the best of luck in sorting out this issue. --RaVNzCRoFT
