Summary

I use these for my Apex 1 equipped Gravel Bike.

I found that I needed thinner bleed blocks to remove some of the squishy feeling that SRAM brakes tend to have. Using a thinner block leads to overfilling of the brake lines with brake fluid, so the pads sit nearer to the discs and brake feel is a bit more direct, but the brakes are more prone to rubbing on the rotor.

The block is designed so it can be used in 4 orientations. The thickness is debossed on top of the part.
The 4 holes can be used with the brake pad screw to prevent the block from slipping out during the bleed procedure.

Possibly useful for other SRAM brakes as well or even other brake manufacturers with some changes to the scad file.
