M249 Front Sight Adjusting Tool (Airsoft)

I do NOT own this Airsoft rifle, but I remixed this model to be easier to print as well as slightly more stable as the Thingiverse print snapped almost immediately. I have not yet tested this design, but I plan to once I go to my friend's house(he requested it). It is pre-oriented and should be printed at a high temperature and with a filament of a high stress rating, I typically default to petg-cf for these applications because they often go on sale for about $24/kg. A better material would be PPS-CF, or possibly Nylon-GF. But I do not have access to those materials, nor have the proper modifications to run PPS-CF. Please suggest better filaments, or model improvements in the comments.
