This is where I am right now.. Unfortunately customs duties prevent me buying large parts from abroad .. So I have to go with local resources and it is a nightmare to mix and match.

In almost every field or domain, interoperability and standards are the main game stopper so its a big win and benefit what openbuilds is offering through their products.. The standardization for a common purpose! Thats where the real value is in my humble opinion.

Anyways.. Used 40 by 40 extrusions here with 10X40ies from the local manufacturer.

Once again i am playing with ideas.. This is not final..

 

Backplates are 10mm 7075.. Side plates are 5mm 6061.. Y gantries are 15mm 6061. Other gantries are 12mm.

10x40ies are only to give a flat thickness required.. 40x40ies are real thick and heavy (made of 6063 and 1.98 kg/m)

Also 40x40ies attach with 4 M6 bolts to top and bottom. The mid hole is M8 (great to use for air, oil tubes etc)

 

Thank you Rob,

This is the Z axis..

 

I also plan to use a custom designed/made anti backlash nut (as illustrated on the right). I think it should help..

 

Yes I ve seen his build and videos.. He is doing a fantastic job!

 

Theres still work todo.. But this is where the Mod6 design is after valuable inputs from Rob & Phil..

 

I had to put this project "on hold" after current conditions.

Designed two sterilization cabins and built the one of the prototypes instead.

One for daily items that facilitates an UVC lamp for items like cell-phones, keys, wallets, cash etc. together with automated hand sanitizer spraying function with sensor detection. The UVC can not be operated once it detects movement inside the cabin and the doors of the cabin are not closed. The sanitizer however will spray ethanol based sanitizer on hands when the sensor detects movement inside the cabin. Unfortunately mass production has not been possible due to logistic limitations.

The second prototype is for whole-body sterilization. (I have not built that one due to costs involved). It requires relatively more expensive UVC selection (wavelength) to prevent hazard to human eye and skin.
I turned one of the small bathrooms into a sterilization unit instead and using the place for disinfecting clothes shoes and anything else once a family member comes back home after going out for mandatory errands (shopping etc)

 

That is so true. The idea here is to kill the ones those are on your hands through sanitizing liquids.
It would be not so good if all body is exposed to artificial UV light. In that sense my only intention is to kill gems, bacteria and viruses on high risk items we use daily. (cell phones, keys, wallets, banknotes etc.)

It is a known fact too much steril environment causing diseases like asthma due to lack of certain flora is not taken into human body so the immune system fails to reproduce "good guys" to prevent it happening.

 

Yes the target surfaces should be exposed to the UV light for a given time depending on the distance, power/intensity wavelength of the UV light source. A grill like shelf to hold the items up and reflecting surfaces to cover the bay should do a better job in that sense.

Best of luck to all of you guys. Stay safe and lets get rid of this monster asap all together.

 

As soon as this craziness is over. Right now the economy and exchange rates are too bad to cope with..
