I have a Bowflex SelectTech adjustable bench that has been in use for over 10 years. The leg brace foam pads are held in by these soft plastic inserts that have since become worn, so the pads slip off constantly. Replacements were modeled in Fusion to replace them. These were printed in TPU and PLA with a .6 nozzle with no support needed. Both work great, but I would recommend TPU if the bench will be in a hot area or bumped into often.
