GALLERY

This is the most current design iteration featuring a housing 3D printed in PLA, servos installed and cable management. All printed parts are mechanically assembled with heat-set threaded inserts or self-threading screws.

This angle shows one half of the shell for better visibility. Small rings on top of the recorder offer space for set screws which keep the recorder from spinning which would prevent the servo arms from fully sealing the holes.

Another angle of the servo mounting assembly.

These are my first iteration of the servo arms which are printed in Elegoo water-washable resin. Resin was chosen due to the high fidelity needed for proper contact. They're attached and screwed on to each motor after being given a 1mm layer of silicone on the bottom.

In order to better tidy up cables, I've modeled an altered version of the main housing that features access points for wires to be routed along the sides and down to the bottom as can be seen here. The channel pieces will be screwed into the side of the housing. This version also features some other marginal improvements such as reworked clearances for mechanical parts to reduce post-processing time.

Another view here shows screw holes and cutouts which will allow wires to be routed.

Here you can see one of the servo arms in CAD. Modeled with clearance for the silicone, each arm is different as the recorder features a slight taper along it's length. This means that the base of each pad needs a different contour to be modeled.

After cleaning and curing, here you can see the arms successfully installed onto the servos. Once the silicone sheets arrive I can glue them and begin testing servo movement.
