thumb rest for picatinny front rail on a pistol

Hi,  it's my first part that i put on any site. Please be juste and gentil with my work.

first of all, it a thumb rest for pistol. i design it with solid edge 2023 and i printed on my Elegoo 4pro with PLA. No need for support. The bolt and nut that will fit on is a M4 with a allhand key head.

attention!

multiply by 2540% the scale to match the right dimension because my solid edge dont do the right scaling. i also used cura for slicing. This part take abut 28 minutes to print on my elegoo. it will be more slow ont prusa 3+, elegoo 3 max end lower.

For the bolt and nut on that part it's a M3 40mm long with a cylinder head and a 3mm soket for a allhand key. I make this correction. 

i steel need to try it but with the stifness of the PLA it will not break.

thanks for you future comment and add on.
