Glock G19 / G17 TLR-1 Light Bearing IWB Holster

Update: Revised hardware recommendations to achieve a more optimal range of retention. 

You may have seen the mold version of this design, “Glock 19 IWB Holster, Split Mold, Right and Left Hand Compatible”. Since not everyone has the tools or experience to vacuum form holsters, I decided to adapt it for 3D printing. After receiving great feedback on the original mold, I wanted to make this design more accessible. 
 

Note: This printable version is currently available only in a right-hand configuration, and is not compatible with the TLR-1 HL-X

This model is a printable version of a thermoform-style holster, purpose-built for makers who want to print, fit, and carry. Designed for the Glock 19/45/19X with a Streamlight TLR-1 

(New profile added for full size models: G17/G47/G22/G3)

Features

• Right-hand IWB design with full-height sweat guard.
• FOMI & Dual RCS hole patterns for wide compatibility with most IWB belt attachments.
• Mounting holes for the ModWing LB concealment claw (recommended) double as adjustable retention points. Includes a third hole behind the claw head for added stability - replace the short factory screw & nut with the specified size below.

• Built-in concealment geometry: raised offset behind belt attachment helps pull the holster tighter to the body, even without a claw.

   

Material & Printing Tips

• Recommended material: PLA Basic is fine, PETG is recommended. For users expecting excesive heat, ABS or PET-CF is recommended.
• Supports: Required and can be stubborn dependant upon print orientation and support settings. Clean carefully to avoid over flexing and snapping the sight channel - applicable for more brittle mateirals. A needlenose pliers is quite handy here.
