Sliding window spring pin piece

I really don't know what this piece is called, but on my sliding windows, there's a spring loaded pin that keeps the window in the track. If you pull the pin down, you can take the window out of the frame. The guide pin on mine broke and I could not find a replacement part anywhere, so I designed it in tinkercad and printed it.

6/24/25 edit - I added a few new variations. The pin on the original design was too narrow and after years of sitting a little wonky in the channel, it broke. I beefed up the pin with a few different widths. i think the 7.5mm one ended up fitting my window best, but your mileage may vary. I also had to model one of the pin holder pieces that also broke on my window, so that's included as well.
