This print holds two 16oz pump dispenser bottles. I used shampoo and conditioner from Suavecito but the bottles are mostly generic.

Unscrew the pump from the bottle to feed through the mounting hole.

I used VHB tape to hold this to the wall of my shower. Clean surfaces first and mount without any weight for 24 hours to let VHB cure and stick well. I've also used clear nano tape and had good, immediate success.

Printed in PLA upside down so rings are against print surface. The rings are the weakest point so it's best to get several walls around them. No really dense infill is needed so 12% or so will work.
