Hi everyone. I am back with Rev 2 of the PLA75. Let
me get you a changelog:
- Raised front height by 1 mm to allow for more flex on the bottom row, and prevent screw in stabilizers from banging the bottom case. As a consequence, it changed the typing angle ever so slightly from 4.94 to 5.35 degrees. This should be a welcome change as it seems that people enjoy something closer to 6-7 degrees.
- Increased the relief cut around the plate this is just more insurance that the plate is completely isolated from the case.
- Raised edge height (with respect to keycaps) on Rev 1 I could see the keycap bottoms if I looked at it from certain angles and I didnt like that. Moved it from 7.25 mm from the top of the plate to 8 mm. I also reduced the chamfer as that as adding to the adverse visual effect.
- Backed the bezel off from the keycaps a bit more. There were no issues with keycaps rubbing on the case sides, but it was a little too close for comfort, and having a little more experience with 3D printing now I decided to add just a tiny bit of wiggle room. Flipped spacebar folks rejoice.
- Made the f////// screw holes bigger. Not sure what happened on Rev 1, but sometimes printers undersize holes. (For those interested in why, imagine if you had to approximate a circle with a pentagon, and then drew the biggest circle you could within said pentagon. That is how CAD files are converted to 3D printing files, as they are just a collection of points in space that connect to one another, and you are going to want to approximate circles to save on points/data.) TL;DR, oversize your holes even more than you already did.
- Made the f////// nut slots smaller. The nuts friction fit now. No more glue/tedious assembly. Just give em a good shove and forget about them.
-
Fixed plates. KBDfans had the wrong layout specified for
the split space on the KBD75 PCB, and I made the plates
according to that ☹. I also discovered a new weird split
space layout that isnt documented. See the KLE below for
all supported layouts. I also made them white for better
RBG brightness.

Here are some things I am experimenting with for this
coming GB:
-
Back cut to make the case sleeker and less blocky. Let me know if you like it
-
The option for a weight. Target is 2.5 lb (1.1 kg) which would make the whole board around 3.5 lb (1.6 kg) kg, and 4.6 lb (2.1 kg) built.
-
I am experimenting with flat sheet gaskets instead of cord. Got some ordered today and we will see if they make any difference. I suspect they will be a pain because you cannot get them to stay without glue, unlike the cord which just snaps in and out of the wells.
I plan on running this in the next month or so. Everything I need for PCBs, plates and cases is up and running, so things should go smoothly with a very fast turnaround time. I am printing the cases here in Canada this round, with some help from smyjpmu of protocases.com. I am sure that the quality will be on par with keyboardbelles from Rev 1 😊.
FAQ
More
Ne spots avail?
He has no problem doing a fulfillment
of 75 units, so there should be more spots this time than
previous.
Cost?
I am aiming for the target of $185
for a full kit, which is what Rev 1 was, however
keyboardbelle had a larger operation which allowed for lower
printing prices, so the change in case maker may result in a
small price bump.
When?
After a final round of
prototypes and some administrative stuff I should be good to
go. Call it a month.
How fast do I need to be?
Rev
1 was 50 spots, and sold out in 8 hours in Oct 2019, for
your reference.
