You need a printer so you can understand the strengths and limitations of the physical process and results and design accordingly to shape and strengthen as needed. Its knowledge and experience you need to struggle with in order to understand the reality of the likely result for real world use. You still show the ignorance and have an unrealistic expectation as a result. 3D printers are not all the same and results differ depending on how well setup and tuned the printer is. Particularly how good layer adhesion is, how the temperature and humidity in the room the printer was used will widely effect overall strength and how the infill is handled will change dimensional accuracy. Its like people seeing a cheap telescope at Aldi and thinking that’ll be awesome but the reality is far from the truth, its more likely an experience that will turn them off getting a suitable telescope and astronomy altogether. You’re in the same “ head buried in the sand” position. Sure you can build a model and send it off to someone to print but it could look ok on your screen but have errors due to the software and how you built the model that makes it unabled to be sliced for printing, even if its works it may not be strong enough to be relied on to support weight. Which is why services like Shapeways are expensive they have proper 3D printers not the poor consumer levels ones that are not very good for anything more serious than a trinket. I’m yet to see an affordable and reliable consumer level 3D printer but we’re getting close. They are still mostly chinese built kits from chinese parts with poor quality control and work well for a bit at least until something goes wrong (usually due to using cheapie filaments or electronics frying). To build an effective model requires experience of printing, not just being able to build a model. Still a short cylinder is easy enough and will work out but prepare for it to fail since you clearly dont comprehend how it can fail due to zero experience. Its not as simple as you think. I won’t offer my prediction beyond it’ll go together and work for one day. I prefer my prints to work forever not just temporarily for a little while.

Thanks Steve for taking your time to try and help I do appreciate your input.
Perhaps my style which is to always play down my knowledge has given you a somewhat false impression and so I feel guilty that I may have mislead you in my effort not to throw my weight around.
I am totally aware of the various issues and I have been following the game for many years and it is perhaps my unexpressed understanding that has you maybe putting me in the wrong box and moreover it is indeed my understanding of the realities of cheap printers that has seen me not rushing in and buying a cheap two grand printer...indeed same for the reality of expensive printers for me as a prospective buyer..I don't buy media hype you see..if I buy one it would be functional at a level that would offer genuine benefit and as you well know we are talking big bucks.again but it is not the money it is the learning and Expeience I know that must be gained that has me still not getting into the game...it is that understanding that caused me to suggest it is best seen as a hobby ...
The only reason I came back to thinking about printing was for the RASA scopes one needs a cable management system as the cables pass in front of the light path..it seems standard practice with RASA owners to print a unit to manage the cables..now having spent a whole day making one out of plastic from the bottom of a Woolies shopping bag I came up with a better design that would be printable and then I saw this post and as I often do popped in to offer my views ... anyways like I said the best way to build my "better" unit would be to make it up in cardboard then saturate the cardboard with resin ...I have made many parts over the years this way and the more I think about it and particularly with your timely reminder and given how my head hurts learning Blender cardboard plastic is the way to go...a major benefit of this system is you, most times, can do your plans on lite cardboard then cut it out and turn it into a plastic finished model.
AND the only reason I make something these days is if I can't buy something ready made..the only reason I cast in alluminium my pier to mount fitting was I did not think anything on the market was half decent...and yes many molds that did not cut it and failures but guess what my mount now sits upon.
I was going to build a fantastic mount that I designed to be built out of cardboard and resin..but with a overlay of carbon fibre..would it work?...of course but it would probably take several builds to develop such a revolutionary approach...and I would but I have now my EQ 8R which takes away the need to build something...
The thing I was thinking of is in effect a circle or in Blender speak a cylinder approx 11.5 inches in diameter, u section to carry cable with a semi circle "half cylinder" 5.5 inches in diameter attactched to bring the cables over the light path..a further section carrying the cable up the side of the camera would be sensible...can you make me one please..money is no object..spend what you like on it but I am prepared to pay $50.
Have a great day..nice hearing from you.
Alex
