About this 3D model
Collection of holders for cylindrical items. The idea is to use a bottom part and one or more top parts to keep the item in place. For the bottom parts, in addition to the regular version, I have added a variation with cutouts for items, that require e.g. a cable. However, these might be less stable than the full parts. Fusion 360 file is included in case someone needs a specific size. All files print without supports in the given orientation.
