Download Free 3D Model 15W Stereo Amplifier Case 3D Print Model

Summary
This is a case to a 15W audio amplifier board that can be found on eBay, AliExpress, … such as https://www.aliexpress.com/store/product/Hot-Sale-1pc-TDA7297-Version-B-2-15W-Digital-For-Audio-Amplifier-Board-Dual-Channel-AC/1959068_32666077241.html?spm=2114.12010615.0.0.7a894502EdjFEn . I use this amplifier for an Asus Tinker Board.
You will also need a mini toggle switch, a barrel power jack and a 1/8″ stereo jack and some 22 gauge wire. The hole for the power jack is 8.25 mm. The hole for the audio jack is 6.25 mm.
The board is held in the case with one 8 mm, M3 screw on the front. Since the screws in the back are difficult to reach, using 20 mm, M3 screws help. Then with tweezers, it is possible to put the nut on top of the screw. The heads of the screws are on the bottom of the case.
