For use with the  popular style of home pulley machine: [https://strongway.co.uk/products/strongway-wall-mounted-cable-crossover](https://strongway.co.uk/products/strongway-wall-mounted-cable-crossover)

Tight fit to the top uprights to prevent the pulleys hitting each other and damaging them. 

You can either:

• dismantle the machine and print the stl as is, sliding over the uprights.

• use the 3mf, to print in two halves held together with 4 M3x12 bolts, per part (as pictured).
