The color of my printed overlay is different than what it appears on the screen. I'm sure there's a color calibration/correction needed for both my monitor screen and the combination of printer and material.. but I just didn't need to make more problems for myself at the time..

It's a bit unfortunate for others that want to modify this that the geometry of all the pieces is derived from the OpenSCAD script. But that turned out to be really handy when tweaking things as it made all those rows and columns of keys much easier to line up with each other, rather than tweaking them by hand in Inkscape. If OpenSCAD could generate 2D output with colors, I would have preferred to keep it all in there, but these are the tools that I have. I was already using OpenSCAD for my 3D printing time-wasting pursuits, so it was a handy tool for doing the parametric modeling of the dimensions.

I'll make a new posting here when I've incorporated the updates.

Sounds good, and thanks again!

I have been doing a bit more experimentation with Inkscape here. I did manage to create my own keycaps covers (blanks) for the 6 2nd menu keys. Also played around with colors a bit more (in anticipation of getting the 39gs (hopefully this weekend it will arrive)). I like the near-black background for the 50g, but I think this will look weird on the white/gray of the 39gs. I was thinking of doing a nearly white background (just enough color so I can see the outline after printing) and modifying the various colors so they still contrast with the white background.

If you want to save some time over the weekend, I think all that I would personally need to continue experimenation would be the "v7" svg that includes your row spacing and cutout size tweaks, since I have figured out how to crudely add those extra blanks in there. I am just hesitant to go much further with the v6 version, since you mentioned that some of the keys interfered with the openings.

OpenSCAD scared me off as I was looking for a decent CAD option for at home use with my 3D printer. I have been using ProE (now Creo) for about 23 years, and ended up settling on Fusion360 for simple CAD projects for those times when I don't have access to my work laptop (which is almost "never" with the working from home routine).

Thanks again for your efforts on this!

RE: newRPL keyboard overlay
I've posted links to the files off my blog post over here. This points to the same PNG file I posted the link to before, and I've also added the Inkscape SVG file and the OpenSCAD script and resulting SVG file that defines the geometry that is incorporated as a layer in the Inkscape file.

I would be curious to hear how well an inkjet printed version of this label works as compared to my laser printed with another thin layer of clear vinyl sandwich approach.

Awesome! I will dive into this and give it a shot. My plan is to print with an inkjet printer, and I bought a can of clear spray acrylic that I intend to use to "seal" it. (I don't have any of the clear vinyl sheets to use as a top layer, but I have considered that option.

I was pretty happy with the acrylic spray treatment when I tried it, except for the toner from the laser printer flaking off at the edges of the cuts. It may be that the inkjet ink will bind better and not have that effect. I think it will have a better "feel" since the keyboard button labels will be thinner.

I spent a little time trying to pick the colors.. ultimately, the darker green I ended up with was inspired by the HP 48 that I had. But the black scheme on the 40gs also would look sharp and provide better contrast I suspect.

RE: newRPL keyboard overlay
Here is the result of my first attempt at applying the vinyl overlay...

It went OK for the most part, and looks really good (almost stock), but I am finding that the circles for the directional arrow keys are very difficult to cut neatly. I also found that pattern of holes seems to be a bit "off" positionally (in the vertical direction). I ended up doing a little bit of surgery on those holes while the overlay was partially applied (from the tangent key row downward it was already stuck).

The down arrow for me was hitting the top of the cutout in the overlay (that hole seemed to be too low) so I crudely trimmed a bit of the material from the top of that hole. I need to go and make sure that I didn't inadvertently move something (which I don't think I did, since I never touched that area of the template). The end result was that a bit of the blue-shift CUT label was cut away (the irony!)...

EDIT: In case someone wasn't following this whole thread, I am using a modified version of the template, where I added blank keytop labels for the 2nd/3rd rows of keys, adjusted colors to match the HP50g, and did a bit of adjustment on the colors of the RS and LS shift colors to contrast well with the dark background of the overlay.

Thanks for posting the photos of your variation. Your darker color scheme is starting to grow on me! It enables the lighter "shift" colored labels with good contrast.

That's something I fiddled with quite a bit, which took me down the path of darker shades of green. Might as well just go to the black color, or something very close. I think that would still look OK on the while body of the HP 39gs. Maybe if I expanded the label size a bit more to cover more of the face and extend closer to the edges?

Or as they say, "better" is the enemy of "done" and this could be done enough for now..

Glad to see this was useful for others.

RE: newRPL keyboard overlay
I have a separate SVG file I created for the 39gs, just waiting for my eBay order to work its way through the dumpster fire that the USPS has become. (Apparently Priority Mail takes at least 5-6 days to get from North Carolina to Michigan.) Once I have that in hand I think I will have a better sense of how the black vs nearly white backgrounds will look on that 39gs.

I used a pale whitish gray for the background and black print for the keytops and unshifted labels, with alpha being orange, LS darker blue, and a reddish color for RS. I also attempted to shift the openings for the direction arrows up by 1.5mm and adjusted the positioning of the labels associated with the arrow keys accordingly. I just hope those keys aren't in a slightly different location for the 50g and the 39gs!

Thanks for your work on this template, it will indeed be very useful to a lot of people.

PS: You have more newRPL calcs than me!

Thanks!

The USPS seems to have lost my ebay 39gs shipment, so it will be a while before I can try my variant for that calc.

EDIT: I have to give all the credit to lmamakos for creating an excellent template for those of us who want to take the time to tweak things to their liking. The source SVG file is a gold mine for that...
