CED7000 Shot Timer TPU Cover

CED7000 Shot Timer TPU Cover

What is this about?

I recently got a CED7000 shot timer and wanted to have some protection for it against drops or bumps. I found a design for a cover on Thingiverse, but although the timer did fit into it, the cutouts for the buttons didn't really fit. So I modified it in the slicer, enlarged the cutout for the display and front buttons, for the top buttons and the microphone slots on the front. In addition I added a cutout in the back for the lanyard connection point, so it is still possible to use it.

How to print?

The 3MF is already set up and ready for printing. I added manual tree supports for the overhangs on the top and microphone cutout. I used a single wall and 15% cross hatch infill (see last picture), which gives a bit more flexibility and “squishiness”, which not only makes it easier to put the cover onto the timer, but also absorbs bumps better. If you want a firmer cover, feel free to increase the wall count or infill percentage.

I printed this in cheap generic TPU from Aliexpress. So any TPU should work. Just make sure it's dry, as usual with TPU. Otherwise there will be a lot of stringing, especially on the transitions between the support and the cover.

Special considerations?

There really aren't any. Just load up some (well dried) TPU and fire up the print. Everything else should already be taken care of in the 3MF.

When installing the cover, put the timer in through the large cutout on the front, push it down and the fold the top edges over the timer. The last part can be a bit tricky, especially if you increase the wall count and end up with a stiffer cover. But it is doable with some elbow grease :)
