About this 3D model
Here is a cylinder holder. This is the small one with an inner diameter of about 3 cm. Mounted using the T-Clip System by Line Arc Line . You can also use T-Clips mini by capze or Low Profile T-Clips by tchoupshop to fit flush. The clips come in two versions - one for black/white Skadis boards, and one for unpainted ones (not included here; please download from the creator). I made a T Clip tool to make turning the clips easier, especially the flushed version .
