(JRC-IFG1D) INCLINED FRONT GRIP, SBR (PDW), HANDGUARD

thingiverse

UPDATE: (2016-06-29) Added STL files where IFGs have no support pillars at the rear edge of the model. UPDATE: (2016-06-28) Added a support pillar at the rear edge of the model for improved post-print structural properties, aligned with its longer brother, JRC-IFG1C. Redesigned part width to feature uniform thickness across the entire length. Included an additional 0.2mm in the bottom portion of the MIL-STD-1913 rail opening for better clearance. This is a "work-in-progress" prototype of an Inclined Front Grip (IFG) designed for use on SBRs (PDWs), featuring a MIL-STD-1913 (Picatinny) Accessory Rail. An instructional video can be viewed on the SBS Extensions YouTube Channel by clicking the link to watch it. The video showcases a preceding IFG variant by SBS Extensions, JRC-IFG1C. Currently available are three STL "GRIPS" models: "GRIPS 0" - No textured surface with an SBS logo on the front "GRIPS 1" - Chevrons textured surface on the sides with an SBS logo on the front "GRIPS 2" - Countersink textured surface with an SBS logo on the front Thingiverse thumbnails and YouTube video display the "GRIPS 2" version. Print Settings: Printer Brand: MakerBot Printer: MakerBot Replicator 2X Rafts: Doesn't Matter Supports: No Resolution: 0.3mm Tested Infill: 80% (Minimum Recommended) Notes: SUGGESTED ITEM PRINT SETTINGS: 80% to 100% Infill 3 Shells minimum No Supports required No Raft required Hot End: 235C [based on MakerBot ABS] Hot Bed: 113C [based on MakerBot ABS] Filament diameter: 1.77 mm [based on MakerBot ABS] Retraction: 1.3 mm [based on MakerBot ABS] PLEASE NOTE: It is strongly recommended to print the bottom of the grip parallel and flat with a print bed, especially for all STL files with support pillars. Do not use the actively functional part where the installed device has layers parallel to the 1913 accessory rail, as it offers the weakest mechanical properties. STL files were saved in their suggested printing orientation; rotate around the Z-axis as required. The latest prototype part was designed using MakerBot ABS filament. Print Speed for ABS filament is based on Original Prusa i3 Slic3r settings and translated to MakerBot. An enclosure was used to print with ABS filament. No active cooling is required when printing with ABS filament. PLA filament is not recommended for final use; only use impact-resistant filament types such as ABS, ASA, PETG, etc.
