thingiverse

This is a table top radio built around this module:http://www.ebay.com/itm/252493815508 This may also do but have't tested:http://www.ebay.com/itm/131571817336 And this speaker:http://www.ebay.com/itm/332125249549 Don´t buy cheap speakers, this is an original Tivoli Audio speaker this will make your radio sound very good and has the correct specs for the module. The antenna can be internal or external with a panel F-type connector. Internal, 75 cm of copper unifilar waxed or insulated wire winded around the bass reflex and power plug in the back will work very well, tested. The power plug is a common dc connector:http://www.ebay.com/itm/332068139283 Glue it with hot glue. The switch can be something like this:http://www.ebay.com/itm/182050318772 There is a version of the back with a hole for a 6mm dc switch in case you want a switch. The box has 4 spots for these rubber feet:http://www.ebay.com/itm/112253048709 If you print it you will have to fill the case with some foam to reduce the midrange resonance. This radio is inspired by the Tivoli Pal radio but with the case style of the Tivoli Model One. // ´ve printed it but I´m still waiting for the module, when I have it ready I´ll post a video here.// At this point I received the radio and assembled everything, its working very well with great sound, will post a video sound, great clarity and enough volume. Issues: The module is stereo, I only connected one channel, left, the correct way to do this would be with a summing circuit, not big deal: Here:http://www.rane.com/note109.html Its the stereo to mono summing box. Print Settings Printer Brand: Prusa Printer: Prusa Mk2 Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0,20 Infill: various Notes: Front and back, honeycomb 30%, 3 walls. Box, rect 15% or less, 3 walls. Buttons and grill should be a little more dense like honeycomb 40% or even more. Post-Printing Another issue is air tightness, this is a bass reflex cabinet and the speaker won´t produce much air movements, even so, you can glue the front panel with silicone and maybe put a thin line of silicone around the inner perimeter of the box before closing the back panel for the last time. Another issue, that will depend on your printer, is the tolerances between the box and the front and back. On mine, after trimming the first layer all the parts could be fixed well. The design has a tolerance for this. How I Designed This Fusion 360
