How to connect the mosquito to your design? #1

Closed deuse-x closed 3 years ago

deuse-x commented 3 years ago

Hi.
I just made your great design for the CR- SE Mosquito_And_Orbiter

I think I will have to buy some inserts to connect it to the strain gauge.

But I can not find a way to connect the Mosquito to your design. The holes for it are way to big. I can't put a insert in. Can you help please?

Thank you for your design and letting us use them.

Both sets of holes should get melt inserts. I will check whether I made a mistake in the sizing.

I don't own a Mosquito (clone) myself so haven't been able to test it.

Thank you.

I just bought these https://www.amazon.co.uk/threaded-embedment-assortment-ultrasonic-embedding/dp/B08KVWYTN1/ref=sr_1_28?dchild=1&keywords=brass+inserts&qid=1624393548&sr=8-28

Hope they are the right kind. I will post pics.

Thank you again

These are not actually hot-melt inserts but injection molding inserts (they often get sold as hotmelt inserts unfortunately). You can either get the real ones (these are the ones I bought https://nl.aliexpress.com/item/1005001553234012.html) or i adjust the hole sizes but that will be tricky as there is very little room to the filament path. Hence If you reprint you will probably have to drill the filament hole to get the Bowden tube trough. I have a set of the ones like you bought, they don't have M2.5. However if extrapolating from the M2 the shaft of the M2.5 ones should be 3.3mm. The holes are 3.2 and print 3.0 (due to the molten plastic moving inward a little). If you happen to have a 3.2 or 3.4 mm drill you could increase the hole size a little. I uploaded a version with the increased hole size to accommodate the IM inserts. I have not increased the size of the holes for the Orbiter or strain gauge as those seem to be a bit more size tolerant when I understand you correctly. I will include a bit more text and a video from CNC Kitchen to explain this better.

Thank you so much.

I just bought the ones from AliExpress. It's the 300 set I got.

I will print the other one now and let you know.

Have you got a youtube channel?

KoenVanduffel commented 3 years ago

I don't have a real YouTube channel. I just posted a 10:24 Benchy today which is my first ever YouTube post https://m.youtube.com/watch?v=kOTIyuHyYVc Quality is quite poor as it was just the Raspberry cam recording it...

Never seen anything like it :)

Well done dude.

Sorry to bother you.

But which set did you buy off aliexpress? I know nothing about these. I've just noticed that there are all lengths and sizes.

Thanks again.

When I bought them i didn't know anything either :). I bought set nr 4-20 which I though were the sizes I would use most. i bought a larger bag of M3x4.5x3.0 and M3x4.6x7.0 from this seller (watch out he also has M3x3x4.2 so the same screw thread but smaller outside diameter, in itself no issue but you need to make the holes the correct size) https://nl.aliexpress.com/item/4000958639502.html There are however quite a lot of sellers, probably also local ones. the thing to watch out for is the narrower tip and 2 rings with angled nudges. The IM ones have straight nudges which is OK but they are at the sides which makes mounting difficult and pushed the plastic in front if you push then in too quickly. So be slow, let the plastic melt and gravity should do the work.

I will get the 4-20 one for starters.

I'm old and my mind is not working right :) So sorry about all this.

No problem, this also teaches me where i can improve if only in the explanation part (which i still have to make for the biggest part anyway).
