This is a phone stand with elevation adjustment capabilities which is done by a worm drive.
All fasteners used are M4 and some parts may need to be joined together with superglue.
The Worm Drive and Gear must be aligned in a specific orientation.
For Assembly instructions please refer to the exploded drawing.
Note:If you are having trouble printing the worm drive as a whole part, you can try printing the alternative Worm Drive 1 and 2 with the key first, then superglue the 3 parts together. You may need to use a file or knife to refine the part edges to get them to fit together depending on your print quality.
The Arm, Worm Gear and Worm Drive may require supports depending on your printer quality.
Some file work may be required for the Worm Drive to smoothen and refine the shape. The M4 Nut that goes into the Worm Drive must be superglued in place and the screw used to connect the Knob and the Worm Drive cannot be shorter than 60mm.
When assembling the Arm to the Worm Gear the screw could threaded in place via the side of the bracket.
Please refer to the exploded drawing for assembly details.
