in my country (Croatia) it is commonly used in sets for DVB-T receivers, MaxTV, EVO TV and other subsciptions that require a receiver
so my TV remote for a receiver broke practically in half (only the plastic parts, the electronics were fine) - the options were to buy the whole set with the receiver that I did not need or to buy it from abroad, pay for shipping and wait 1 week, not to mention I would toss away a perfectly usable board…I decided non of it was a good option and I started to design my own shell for the circut board
| DESIGN DECISIONS |
it is a simple design, the premisse was that it had to be easy and fast to print
also it had to be easy to assemble and disassemble if needed - no glue and no aditional screws
| PRINT SETTINGS |
usualy I do not like to include 3mf or GCODE files because I do not know what kind of printer/filament/general setup do you use, SO BE CAREFUL WHEN USING THIS 3MF FILE - CHECK WITH YOUR OWN SETTINGS SO YOU DON'T BREAK ANYTHING ON YOUR MACHINE!
no supports are needed
General settings:
0,10 - 0,20 mm layer height - depends on your preference
10% Cubic infill - it should be enough
brim (if you think you need it)
3 perimeters
| ASSEMBLY |
there are 3 files that you need to print (01_Top, 02_Base, 02a_Base_battery cover), one optional part that you can print (00_Test fit), and you will need some parts from your old TV remote (circut board - with springs, and silicone buttons)
1_Test fit
this step is optional if you are not sure that the shell will fit your controler
for this step you will need to print 00_Test fit
place the silicone button onto the 00_Test fit part and try to push the buttons through the hole
this saves time, filament and frustrations down the road
if it goes in smothly, that the rest should also fit
2_Top part
for this step you will need 01_Top part, circut board and the silicone buttons
place the silicone buttons inside the 01_Top part, make sure that all the buttons have gone through the holes and that the center aligning pin (on 3D printe part) is protruding through
next you can put the circut board in its place
3_Bottom part
for this step you will need 02_Base part and springs for one battery side
in the part there is a small strip between the pillars that secure the spring and make it easier for printers to print the part - you will have to break one or bouth of these for the springs to go through (it depends on the design on your TV remote)
after that its just a matter of putting the spring to the right place
4_Connecting the two parts
now we will connect the bottom and the top part
put the bottom part on top of the top part with 2 of the flaps of the bottom part slid into the top part - but slightly slide it to the bottom so that the bottom flaps are outside of the top part
the bottom part has 6 flaps on its sides, 3 on each with 2 bottom ones beeing slightly wider - these ones should be outside
take the parts and slightly push the other side of the bottom part inside the top part so that the 2 flaps click into the grove
after that you can slide the bottom part the rest of the way into the top part
4_The lid
the battery cover has a slit on the bottom where it can be pushed and then you can just push it into the grove on the top
if you need to open it, you can just pull the lever back and take it off
That is it - do not throw away you TV remote just jet! ;)
