This here thingy is a remix of the BlasterforgePH Nerf Longshot Top Rail of which were kind enough to give to the community. But alas, the community do not have enormous printers!
So DartKrafts took it upon their crafty little fingers and split it up into printable parts for the masses.
It has 4 parts +1. Front Left, Front Right, Back Left, Back Right, plus a little joiner thingy.
The joiner thingy was left separate intentionally as designing it onto one of the rail pieces would put it over 200mm, a common print bed size for most.
Haven't tested it yet, but will as soon as i get the opportunity.
