Spyder extra/tlr feed neck

This feedneck is for spyder extra paintball markers that allows you to use a hopper directly without the old style clear adapter I have a spyder tlr and they look exactly the same and should fit it as well. This was made in tinkered from the spyder Victor feed neck it says to use a gopro screw but the file I found for one didn't have the right size base so I modified that as well.
M5 nut and bolt approx 40mm long for the clamping part
Use M4 pan head machine screw twice as long as original screws to attach to marker
Use support and 100% infill
