HO ballast applicator

Did you 3D print this model?

3D model description

This is ballast applicator for HO railroad. It is suitable for straight track but it is possible to cover even curve tracks. It is designed for standard HO gravel. For assembly you will need some file, sand paper, scalpel and superglue or something glue for PLA. Applicator has slider controll by lever so it is easy to stop appliing proces if it is needed. Asembly is easy just adjust parts with tools and try dry assembly then aply glue on sides, yust dont forgt insert axis first. After you have sides glued together put slider on bottom side and set it to open position with teeth in right position as it shown on picture. Before you glue it together try if slider is moving freely without any issue. If it is OK you can glue sides and bottom together and finaly if you dont do it already put lever on axis and glue it. That's all and you can apply your ballast with this applicator. Thanks for support It helps me to improve my workspace and printers.
