  2. 3D printed Three part Mic Tip project ( Hovi Mix Pa2 )

    in Build Threads Requireing Maintenance

    Posted

    A little update on this!

    I decided to change the bolts to bigger ones as its easier for assembling and it fits just better.

     

    This is how the Hovi's look finished to my personal preference and attached to a helmet. The trick is you can attach the bolts with the base of the mic tip to the helmet and can screw the mainbody with the nipple after then!

    While the exchangerate from Euro to Dollar makes it an unfair price for you US guys I will drop the price to 25$ US-International and 25€ within Europe including shipping for both. I will update this in the sales section! :) I think this price drop will please the hardliners as well as the people who think mic tips are only a luxury item.

     

    Since the price has changed now I will give 10% discount to the customers who already bought some of my Hovi's on their next order!

     

    Thank you guys :)

    Do you have a sales thread for these yet? If not, how much would one set cost?   

     

    Amazing job on these!

    No not yet! I will make a sale thread when I decided which screws/bolts will come with the mic tips. I have some sets ready to ship and the screws with nuts and washers are very close. I just wait a little bit to see if I can find them even closer!

    For prices please drop me pm! :)

    Hey Vaj,  I'm still looking to win a second set of Hovi's with my order... ;) .

    I stopped by Grainger and ordered the screws mentioned earlier in this thread (none of the stores have them in stock - special order).

    When they come in, I'll post a picture.  If they're not the correct screws, they'll go into my shop stock, so no loss.

    Grainger says they will arrive in a few days, so cross your fingers!

    Very cool Aaron! ;) It looks like I found them already but there are no square nuts that will fit this screw thread! Therefore I need to make a compromise soon or maybe I stay with the screws I had from the beginning. I can't wait to see the graingers screws!

    While I am still on the hunt for the correct screws I was able to improve the Hovi's white colour. I can print them in a very deep white now and they are not so "milky" anymore. The original Nipple part looks a bit greenish so I tried to match that! I think I will offer this as an option to everyone depending of what you prefer - white or greenish.

    I found these bolts in Japan. I think they are the size you are looking for. 16 mm long, 4m but these are stainless. Let me know if you need help getting these if all other options fail.

    Awesome work on those mic tips!

     

     

    Pack of 100 M4 X 0.70 X 16 L for just under $11 at Grainger...

    Square shouldered cheese head with a drawing.

    I drive by the store everyday on my way to work so I could verify these are correct.

     

    I'd opt for stainless instead of zinc-plated steel for corrosion resistance...

    Maybe not "canon", but there's a whole lot of hot breath hitting those screws.

    thank you for searching! The ones from Japan look like the ones I already have. They have a rounded head and are close but I hope to find even more accurate screws.

     

    Regarding Graingers: You probably mean the

     

    I can't find a CAD file so if you could look and verify them that would be great!! :) The pictures of the screws often show only similar versions so I can't just order 1000 pieces to find out they are not what I expected.

    This is what I am lookig for:

    These look incredible!  Do you have a price per set?

     

    I get all my hardware through McMaster-Carr.

    You should be able to find anything you need there, plus shipping and customer service are excellent.

    thanks! I think I visited this site before but they haven't real fotos of their products. I should ask them for some samples. I send you a pm for a price - I would like to wait before I got the correct screws until I offer them in the for sales thread. On the other hand its easy to replace them later with different bolts/screws.

    Very nice. I'm actually looking into a form 1+ myself. How is the print quality in general? I've heard both the form 1 and 1+ can struggle with details on vertical sections, but your output looks pretty nice.

     

    Have you tried the black resin yet?

    Well its true the form1+ is a complicated device and formlabs had to replace my printer three times. Many people have problems with laser flare which I think is causing the vertical quality issues you mean. I had even worse problems than that but finaly got a printer that works great. I didn't expect that anymore! To prevent bad surface quality you have to orient the model to an angle of like 45 degrees and the support structure needs to be generated with the longer supports on the hinge side and not on the peel side. There are lots of things to consider and a long learning curve with the form1+. In the end and if working properly the form1+ is unbeatable at the moment in my opinion. I alreay got black, white, clear, grey and castable. Most resins work good for me but it feels like black warps a little bit between the support areas on the underside of the models. It might be that the stronger laserpower used on darker resins can cause this but I don't know.

    I like the idea and the CAD file looks great.

    Is that Rhino software or something else?

     

    At what resolution are these printed?

    Do these exhibit the textured surface typical of most 3D printed items?

     

    Yes this is Rhino! I can print at three resolutions in Micrometer: 0.1 / 0.05 & 0.025. Although 0.25 would be the most accurate I only print the nipple part at this resolution as the mainbody looks better at 0.1 for some reason. I use a stereolithography printer which is way more accurate than a FDM printer. You can still see the layers but the surface is very smooth and detailed.

    Great project. Like to see them in white

    very soon! :)

     

     Nicely done!

     

    Looks like you are in Germany based on the language in your 3D software.. Maybe Germany :D

    thats right.. good eye! :D

    Its long ago since I was active in this hobby. I decided it last too long ;)

    Currently I am working on a project regarding to the Mic Tips of the Stormtroopers we all know by the name of “Hovi Mix Pa2â€. As a Bachelor in Product-Design and with the help of my beloved Form1+ 3D printer I enjoy modeling and creating jewelry and now also the Mic Tips in a very accurate 3 part design.
    I know there are some great creations by some skilled makers here on the forum as well and this is just my personal interpretation with the tools of a CAD program and 3D printing.
    For the 3 part Mic Tips I used pictures of original worn Hovi Mix Pa2 types (aerators) and was measuring and prototyping a lot before I got to these final results. It was real fun to work on this project I always wanted to but never got the time for. Maybe I just show you some pictures and go to more details if you want me to :)
