Hum, I get to print my own eParrot enclosures which means MANY hours of fixing mistakes after one print and before the next print.
Trimming and rounding off edges is all part of the 3D printing experience
My cheap equipment (cost to me about $200) can print one eParrot enclosure per day. Two is also possible. But they are bulky and CANNOT be sent in an e-packet so shipping is prohibitively expensive.
And adjusting the 3D printer's parameters is both complicated and time consuming as the results of a tiny design change can take hours to manifest for each iteration.
If we ever do get this exactly right and people line up 4 wide and 100 deep to buy them (one can dream) then a precision mold could maybe be afforded to cheaply produce these enclosures.
Until then, I'm glad K3 is helping to solve these issues with the "fit and finish".
*** On another note, a recent visit to the HUGE electronics market here in Shenzhen, I saw lots of samples of silicone (or rubber?) push button inserts that are typically found in many electronic "selector" assemblies. Sure, there would be a set up fee and you'd absolutely need to know what you want without any changes as many hundreds or thousands would be cheaply produced after the mold fee is paid.
I'm thinking "screw all that", the future is touch screens. That would be a real game changer but it could also triple the current eParrot cost. It would also more than triple the current functionality. Think on-screen charts and graphs...
I just don't know how to do the Graphical User Interface yet.
