These are parts for a 3-inch strap for a bass guitar. (standard 2" strap parts for a 6 string coming soon.) These parts allow you to use custom webbing, found materials, etc to create a one-of-a kind strap.

The strap buttons are sized for the wood screws that came with the 2 basses I have. You might need to bore them out if your screws are different.

The buttons, slider buckle and end couplers should be printed with high infill for strength.

THE FOLD OVER STRAP ENDS ARE FOR PRINTING WITH AN ELASTOMER SUCH AS NINJAFLEX. Fold them over the end couplers and secure with high-strength contact cement and/or spot weld the 4 button tabs into their holes with a soldering iron.

These parts work well and are currently holding my heavy bass.
