It can be printed without support. The screw holes for installing the circuit board may need to be re-drilled, as they are only 1 mm in diameter.

STP files contain independent sub-objects that are not connected to each other. To print them correctly, you need to perform Boolean operations to connect them. If you want thicker rings, etc., this is done to make it easier for you to make modifications.

Printing instructions

No support is needed, and it includes integrated support. There is a 0.20-millimeter gap between the sacrificial model and the four-axis frame.

The support legs need to be glued together, but the battery holder doesn't require gluing.

Insert the battery holder into place, then carefully add the legs. The legs are less resistant to shear force but more resistant to bending force. The legs are not an integral part of the design.
