SAFETY DISCLAIMER: please make sure you're screwing the barbell mount onto something sturdy. I take absolytely no responsibility on any damage or injury that may arise from the use of this model.

I printed mine in CF-ABS and they're still holding strong many years later. To obtain the honeycomb effect you see in the picture you have to disable the top and bottom layers and only print perimeters and infill. Mine were printed using a .8 mm nozzle so your results may vary using a smaller nozzle. Just make sure to use a lot of perimeters.
