Gigaset A415/A420 belt clip

Gigaset A415 is my first DECT phone that I bought for 36c3 5 years ago, I used it on 36c3, cccamp23, 37c3, EMFCamp 2024 and now 38c3. It's not a great DECT phone, it has no phonebook fetching or belt clip, yet it means a bunch to me. Earlier this year (January) I designed this belt clip for it, which I only remembered to publish now.

It's not a perfect fit (the phone is full of weird curves), I never fully polished it, but it does the job when you use it with double sided tape.

By the way, if you have a Quansheng/Baofeng belt clip lying around, you can also print the variant that uses that instead.

Print instructions:

I think it visually comes off better when you print it with the belt clip facing up. I've had some bed adherence issues today when printing one for someone else (so consider using an appropriate bed or brim), so I tried it with the belt clip facing the bed and it turned out fine, but it comes off uglier. Included a picture of how both variants come out, and a screenshot from slicer.

PLA, PETG, ABS, use whatever, but my pics are random black PLA. I do 100% infill for added structural integrity, I wouldn't want my belt clip to snap off easily.

(I'm not sure which is more structurally sound, facing up will be stronger between phone and the belt clip, facing bed will be stronger in the belt clip itself. I suspect stronger between phone and belt clip is preferable.)

Double sided tape recommendation and installation guideline:

The height (19mm) is same as “tesa Powerbond Ultra Strong Mounting Tape”, and the gap is “designed” for its thickness. Here's one link to it: https://www.amazon.de/-/en/dp/B008JWJYV2 (your local hardware store likely has it for cheaper). Other 19mm high, thick double sided tapes might work, but I only tried this one. I've had it attached in this manner for nearly a year and it's not showing any signs of weakening its grip.

My recommendation is to print the model, apply the double sided tape on it, press it into place, ensure it's a good fit (no gaps on the corners), remove the plastic cover of the double sided tape and then finally stick it on the DECT (right above the speaker, see pictures). I included a side view.

Notes:

I tested this with A420 and it works well enough, but it's a tighter angle on the belt clip (closer to the phone). See pics! (Thanks eventphone for lending me one to try.)

This model may also work for Gigaset E720 and other models but I haven't tried it with that. Let me know if you do!

There's this other attempt someone made that they sell, https://shop.schulz-stephan.de/3D-printed-belt-clip-for-Gigaset-A415-A420-E720, I haven't tried that one myself. Them also needing double sided tape makes me feel like I didn't do too bad of a job with this. If you don't have a printer but want a belt clip, give them a try :)

Fun fact: As you can see, I uploaded the fixed-fixed version of this model. fixed-fixed-fixed version of this file is worse.
