Y-Part does not fit

[sbamueller]

There is a wired thing: The Y-shaped part will fit with the 8 mm tube to the diaphragma but not to the ear things. I printed it twice. I used petg with a prusa.

Hi Sebastian!

Can you post a photo of the issue please?

Thank you!

I have this 8 mm transparent tube, that fits with the diaphragm and the lower end of the Y. But the upper ends of the Y seem to be to small. And there is no use for the 13 mm hose.

Both y-pieces

y-pice lower end and diaphragm tube fit to the 8 mm tube

however not the upper parts of the Y

earpiece fits

13 mm tube useless

A couple of points here:

1. This appears to be PVC tube, which does not have adequate acoustic characteristics. We stopped testing on it early. Silicone tube is what's needed.

2. There are two tubes required:
   a. ID 8mm (OD 13 or 12 - we use 13)
   b. ID 4 mm (OD 8).

From the images, it only looks like you have one size tube here.

If you're having trouble with the tube, happy to send you some tube to play with once I'm back in Canada (mid march)

it seems I bought the wrong tubes in the Bauhaus. I now orderd this from Amazon: https://www.amazon.de/gp/product/B07GDQ37G7/ref=ox_sc_act_title_1?smid=A3MFMWRNQ60S3M&psc=1 and this: https://www.amazon.de/gp/product/B07R2B9SFW/ref=ox_sc_act_title_2?smid=AQ1IBDB6G2RRD&psc=1

Second tube is correct

First tube: I can't tell if you're buying 8mm ID x 10mm OD, which opened first. If so, it's not going to give good acoustic isolation and it will feel flimsy. 8mm ID x 12mm OD is probably the minimum.

So more this one: https://www.amazon.de/gp/product/B07R2BHMRK/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1

Looks good. That one looks like 8mm x 12mm to me.

ok, I orderd those from Amazon. Lets see if I can build them and then write a nice articel about it for https://sbamueller.wordpress.com/2020/02/19/kauft-euch-das-make-magazin-1-2020/
