Injection Molding Design Update
First and foremost, I want to thank all of our backers who came forward over the last two weeks and offered help with the designs for injection molding - THANK YOU! In fact, we had so many people offer to help that we probably haven't got back to everyone yet - so if we didn't respond to your offer, please know we really appreciate it, and we still may ask for your help - but for now we have enough people helping us to have the right balance between new ideas, a high level of experience, and not having so many people working on it at once that we don't get anywhere.
Amazing Design Changes
Of the many people who stepped forward to help, the work of a few - especially one backer - has really led to some amazing changes to the design of the injection molded parts!
Backer Leonid Silverman, as well as two people he recruited to join him have been making the part designs WAY more injection molding friendly - it has been an amazing process to see and we cannot thank them enough for the help.
The idea behind these changes is both to make the parts come out of the molding process with less issues, inaccuracies, and higher quality - while at the same time simplifying the design of the molds needed to make them in order to speed up that process, keep the costs in check, and allow to molds to run longer without issues. (At least that is my understanding!)
Without further delay - here are some of the parts that still have to undergo some final changes, but are very close to being ready:
NOTE: The last part - the Z-carriage had one of the few functional changes in that the bearings are now retained by zip-ties - this makes it easier to make, easier to assemble, and should make for a tighter retention of the bearing vs the old method of a bolt tightened friction hold.
Once again - Thank You to Leonid and his team!
It is my understanding that Leonid is now working on the Y-carriage part as well - and we at Robotic Industries are working on adjusting the head unit to match up with these new parts. After that we'll open up the head unit for redesign for molding as well - and given all the offers for help we had, we are thinking we'll open that up to more people and really get some ideas flowing, as we know that is the most difficult part to mold.

Bed (a slightly older design but still functionally current)
Y-axis/Belt Path (Not shown - Injection molded parts are using larger 5mm bolts to secure idlers instead of 3mm for added rigidity)

That is it for tonight - more media (from the list from last update) and further injection molding updates will be sent out soon - if not later this week, then next.
Thank you all!
