Arrow PT50 Stapler Bump Fire Safety Tip

I lost the original safety tip for my Arrow PT50 stapler.  I was unable to find replacements which was very frustrating.  It was black and disappeared into a pile of leaves.  This is a custom design to serve as a replacement.  It is very tight and won't slip off, you will need a good bit of force to push it on (by design) but it doesn't go too far and has been tested and works great.  I used TPU95A but I suspect TPU 90 would work too.  This might be obvious but the thin side goes against the stapler and the wider side faces out.  Feel free to remix/improve.
