Keltec KSG12 Snap-on Cheek Rest

This is a snap-on cheek rest for the KSG12. After many iterations and test prints, it finally fits like a glove! The following print profiles are for PLA/PETG and TPU 95A/98A and 72D. Its highly recommended to use TPU as the original PLA version developed a crack after shooting some 1oz slugs. ASA was even more brittle and also snapped right away no matter how slow it was printed. PA6CF is a great choice and nearly indestructible if you want a hard shell, but I've had some poor layer quality near the top due to the material getting soft in the heated chamber - your choice of PACF and settings may yield better results.

 

edit: support interface material was removed as it created weaker layer adhesion at the most critical stress points. All print profiles now use single material and AMS is not required. The model has also been updated for TPU print profiles with added reinforcements for increased stiffness and stronger layer adhesion.
