I had some problems fitting the tactile led switches to Karl's button bases. (Most likely because of printer idiosyncrasies, or because of possible differences in design of the tactile switch itself) They were also a bit too loose in the FMC frame for my liking. This made me redesign the bases slightly using Karl's mesh as a guide.
The white clip part of my
switches is 4,5mm x 5.5-5.7mm.
I made them print without supports by adding a complete layer just under the top part. This layer is bridged and can easily be cut out with a scalpel underneath the recess for the switch top. If it's not visible when slicing, reduce layer height. They now fit snugly for me and the switch works better because of the cleaner bottom layer inside the base.
I also made the top hole a diagonal square so that the slight overhang prints cleaner than a circle, it seems not to affect the brightness compared to a round hole. These are printed on and Ender 3 with a 0.2mm nozzle and 0.16mm layer height. Superslicer seems to be smartest regarding the bridged layer.
The link will be posted here as soon as I get an ok from Karl to share my mod
I added modded versions of the action button bases as well to the thingiverse thing so you can get both bases. Will do the round buttons bases next. Gladly saw that Karl has made new line select bases for us with the slightly smaller switches!
[NOTAM3]I have now also added modded bases for the round number buttons.
I have now redesigned the line select switches too to fit my switches better. If my other button bases fit, these will too. The internal design is a bit different too to stop light leaking between the cap and base.
