Toddler MP3 Boom Box

thingiverse

This is a sturdy 3D printed MP3 player to be used by toddlers or small children. All printed parts should print fine on any 3d printer with no supports – orient the flattest side to the bed. I printed in PLA, but should work fine with most filaments. 3 top, 3 bottom, 3 walls, 30% infill, .25mm layer height on .4mm nozzle go warm for good layer adhesion, this should be rugged. The following additional hardware is required: 8x - M3x(8-10)mm Bolts 12x - M3x(14to16)mm Bolts (either works) 1x - 4ohm, 3w speaker ~40mm/1.5in diameter 1x - HW-100 blue MP3 lossless Decoder board with amp 1x - TF card (1-32gb flash card) 1x - TP4056 USB battery Charger module 1x - 18650 battery 8x - ~6" or 15cm wires 1x - round 22mm led rocker switch 2x - 4+ inch zip-ties optional: 2x - 3mm nut inserts (print “back_panel_no_inserts” if skipped) 3x - .25 inch female spade crimp connector terminals (solder to switch if skipped) 1x - .25 inch piggyback spade crimp connector terminal (solder to switch if skipped)
