These little pegs are always getting lost or sucked up into the vacuum cleaner! I made a replacement peg as close as possible to the existing design. Just choose your color (white & black are standard) and print as many as you need.
Updated v2 is much closer in design to the original. I recommend using that model now. I have had no issues printing these even with relatively small contact area on the sheet.
The author marked this model as their own original creation.
