3D model description

These are devices for fixing sandpaper, which are suitable for manual grinding and for machine grinding.
Clamping and tensioning of the sandpaper is performed by rotating the inner cylinder with a slot with an 8 mm hex key. The end of the sandpaper strip is inserted into the slot of the inner cylinder. The beginning of the tape is attached in the slot on the base. If your sandpaper is paper-based and the grit index is high, it will be too thin. Then it makes sense to cut off longer and for better fastening fold it in half in those areas where the tape is attached in the slots.
Two models are made for manual grinding. In the form of a drop with a width of 40 mm, for fine grinding and for grinding in hard-to-reach places. In the form of a bar with a width of 80 mm, for grinding large open surfaces. If desired, the width of the models can be easily changed by simply pulling on the Z axis, in any 3D editor.
Machine grinding can be done with a drill and with the help of angle grinder.
The grinding drum for the drill is available in two versions. With a diameter of 40mm and 70mm. To assemble the grinding drum for the drill, you will need a hex head bolt M6x50mm, which will serve as the drum shaft for mounting in the chuck. And the M6 nut for fixing the bolt. The length of the bolt can be chosen differently, depending on your preferences.
To assemble the grinding drum for the angle grinder, you will only need the M14 nut. Perhaps your angle grinder has a different thread, then you will need to modify a model or write to me. ATTENTIONFor the sanding drum on the angle grinder, in view of the high speed, use only cloth-based sanding paper.
