This ER20 collet storage rack is part of a series of models I made to organize my workshop. At the moment I have storage brackets available for ER collets BT30 toolholders and Morse taper toolholders. I will add more in the future when I need them or when there are a lot of peole that would like to have a specific model. There are a few things to consider when making these, I strongly recommend to watch the video I made about these brackets before making them yourself. The video also gives an overview of the available models.
You are free to download and make these models for personal usage but not to sell without my concent. If you are interested in selling these please contact me and we may be able to work out some deal.
