FNS40 Beta - Heirloom Edition V2 Longboi
-Eng 87
Additional Credit to:
-Main devs: functional frame
-skinnypew: extended length to cover longslide with flush front face
-bluewinter21: OEM stippling and backstrap inspiration
-entire Betagroup

design intent is to improve aesthetics, function, reliability to something which you would trust not to fail if it mattered.

00 - repaired .STEP files & combined for fullsize with standard mag
01 - added retention recess for magspring to aid in assembly
02 - increased the meat around the front pin left side to match OEM design and reduce cracking potential near front pin
03 - thickened the vertical wall segment in front of the front rails to reduce cracking potential near front pin
04 - extended the front face and picatinny section to match longslide profile and front face
05 - added some meat around the front of the magrelease to improve aesthetics
06 - increased the radius of the rear magrelease cutout to reduce slop and make ambidexterity work
07 - matched the rear of the slide profile, both angle and curvature, with transition to beavertail
08 - increased the radii and thickness of the front trigger guard attachment to frame to increase frame rigidity.
09 - deleted
10o - [optional, hardware req'd] added counterbored countersink and increased front rail front surface 0.15mm for rail alignment.
   10c- must print magwell up for rail to be aligned. for magwell down, filing may be needed. 
   10c- 0.15mm layer height recommended
   10c- M5 stainless flathead 8mm LG, mcmaster carr 92125A206
   10c- M5 stainless jamnut (modified via render), mcmaster carr 97258A103. install, but do not tighen till after frontpin installed
   10c- red loctite (apply/tighten after frontpin installed). do not overtighten! could flex frame.
   10c- use ball-end 3mm hex wrench
11 - improved transition aesthetics from trigger guard to the front section (could use more on the back of dovetail)
12 - added meat around the slide release thin frame area for stiffness. exaggerated version of OEM design.
13 - added OEM  or printed backstrap capability
14 - added 90percent of OEM stippling with FNH symbol. symbol can be removed and custom symbols inserted
15 - matched the lower front grip to the front magazine profile
16 - added front grip notches (tiny) just to break up the front surface and draw your eyes to that vs layer lines.
17 - added slight cutout for side of magazine which drags on the inside of hte magwell
18 - added 0.4mm chamfer on the front upper inside cutout to aid in the installation of the slide
19 - added increased meat around the trigger pin on the left side which follows the sweep of the breakdown pin. This should reduce frame flex.

V2 Revisions:
a) removed item 9 as was not stiffening the triggerguard as intended
b) adjusted item #12 with varifillet to get some more stiffening effect on the thin sideframes
c) added item 17
d) increased the radii around the top of the trigger guard and made the fron a little thicker to minimize flex
e) added item 18
f) added item 19
