Autostream Mount Kit for Technics SL-PG3/4/5 CD-Players

This print enables a Raspberry Pi Zero or Zero2W to be installed within a Technics SL-PG3/4/5 CD-Player.

Warning: This modification requires opening and modifying mains-powered equipment and cutting the player lid. Ensure you are comfortable working on vintage electronics before proceeding.

The mount is designed around unused factory holes in the chassis and installs the Pi Zero so that it is right at the top of the case. A 114mm hole-saw should be used to cut into the player lid. This is so that the WiFi signal has a clear path out of the case. The large round cap then covers this hole and is attached using the four spring mounts.

Print in PETG as some spring is required in the clip-mounts for the lid, and for the SPDIF dongle snap-on top.

Autostream logo can be coloured if desired (rotate the model 180° on the build plate to do this, then rotate it back down to print).

Requires:

1. 4x M2.5 5mm screws to connect the spring mounts to the cover disc

2. 4x M2.5 10mm screws to mount the Raspberry Pi with Zero2Go PSU attached

3. 2x M3 self-tapper to mount the bracket into the CD player chassis

4. 2x M3 self-tapper to secure the SPDIF cable grommet

5. 114mm hole saw (or jigsaw) to cut player top panel

Designed for:

1. Raspberry Pi Zero 2W

2. UU Gear Zero2Go power supply hat for the Zero

3. Cubilux SPDIF dongle

The optical cable grommet requires a 20mm hole in the back panel of the chassis and securely clamps a 4.5mm braided cable such as the VENTION Right Angle Toslink Cable.

Recommended print settings:

• Material: PETG

• Layer height: 0.2mm

• Wall Loops: 6

• Infill: 25%

• Supports: Not required

• Orientation: As supplied (rotate model to apply colour to logo if required, and rotate back for printing)
