This is a small cap that helps the use of a smaller ball bearing to still function reliably

I have been using a different sensor on my Voron 2.4 and it has been fantastic, but as of late I have been experiencing a lot of inconsistencies and reliability issues.
Came across this sensor accidentally whilst searching for a different extruder and I quite like the design a lot, however, I could not find any 7mm ball bearings locally, so I ended up just using a 5.5mm ball bearing that I had on hand.
Instead of redesigning the entire sensor, I creating this little cap/pusher that cupped to fit over about 1/3 of a 5.5mm ball bearing and helps to push the endstop switch when filament is inserted. I took inspiration from the WWBMG extruder that uses a similar concept.
I included two versions a 4mm and a 3.5mm as well as the step file if you have a different length requirement.
