Keyboards covers are usually too thin to be a decent mousepad.
Id look for a mousepad that fits into your current bag so probably something the size of the laptop itself
Only downside is abysmal flowrates with hardened steel unless you're using a hardened cht.
Even the clone hardened steel chts are fine since its actually only the tip of the nozzle that wears fast.
If its stopping 10 to 20 seconds there's definitely something in the gcode making the printer hang.
I'd try slicing the file again with a different slicer to be sure.
What printer do you have?

It could be this issue but that wouldn't be material dependent but might show up more with petg since it's more runny than pla.
Enthusiast motherboards still have the ps/2 ports as well. Usually because the usb controller is the first thing to stop working when the bclk gets too high or you're going sub 0 cooling.
Can only speak for the higher ranks of both games but cs2 is currently unplayable above 25k elo since its almost guaranteed to have 1 out of 10 players cheating.
While i only encounter a few cheaters each season in immortal in Valorant.
There will always be limits to how fast you can go. But as long as the average printer is not even close to whats doable there is room for improvement.
Don't go for the TL smoothers but get new drivers instead.
A btt Pico or skr mini would probably be enough for your needs.
Instead of a magnetic pad + plate you could use g10 fr4 fiberglass which is cheaper but both work great.
For a probe see if there's a quickdraw or klicky mod available since it's cheaper and more reliable than a bltouch (clone).
But you should definitely have quite a capable printer with just a few small additions.
You will not get a better system when using servos no matter the price point at the moment.
People have tried and failed just because the software support isn't there yet for 3d printing.
The biggest issue I'm aware of is matching the timing between the extruder stepper and the servos that do the XY motion.
Which isn't apparent at lower speeds but at higher speeds you can notice they're no longer in sync which leads to all sorts of issues and artifacts.
I'm currently waiting on some 3 phase steppers and drivers to test to hopefully get something with less speed deviation than a normal 2 phase stepper and more reverse torque but don't cost too much and are still easily driven by connecting a driver to your boards step/dir output.
A smart strap honestly sounds like a gap in the market. Seen quite a few people wearing a normal watch and trackers.
