If you have a piece that’s 1" x 1" x 5", that’s 5 cubic inches. If you scale it to 40%, you get 0.4" x 0.4" x 2" which is 0.32 cubic inches … about 1/16th of the original volume. Note that 0.4 x 0.4 x 0.4 = 0.064 times the original.
Well now I’m pretty sure my model is hollow. I took the bottom and reversed the face. Then I selected the bottom and deleted it. Now I can see up inside it, just like I would expect to be able to if it was hollow.
I was thinking it maybe on the large size. It’s a big pawn for sure.
Another place for me to check out, thanks!
I’m not for sure I know just what you mean.
By solid you mean selecting all of it and then making it a group?
Yeah, sorry about that. I had planned on doing what you said. Then as I was looking at the bottom I wondered what it would look like if I just deleted the bottom. After I deleted the bottom it looked hollow to me.
So I uploaded your version to Shapeways and the price drops from $100 to $48, wow!
Guess I should have put a hole in the bottom like you told me to do.
What a difference!
So much to learn not only about drawing, but printing too.
The extra cost of a more solid part is $0.28 per cm3 … sometimes substantial savings can be realized. I used your profile and created a 2" tall hollow part that Shapeways prices at $5.30 ($6.30 in black):
You can compare prices and work with someone that you can pick the part up from face to face. It’s often cheaper. You should be able to select someone who is displaying the quality of the prints, and they should work with you to make sure that the part is being printed the way you are looking for.
Even with thickness there are some possible issue with over hangs. Even with allowed max of 45 degs I had to increase model size by ~2x to get supports installed and even then how to break them out is still a issue. Cost is based on more than just vol and since manpower is usually driver in cost you may see that affect.
This is first cut installing at angle on print table will probably not help much
Just for you info pawn_mac1 post.skp (740.9 KB)
One other observation … Shapeways charges a minimum of $4.99 shipping per part which increases the price of your 2" pawn from $5.30 to $10.29 total. If you are making a chess set, you can connect 8 of your pawns with a “sprue” (or “runner”) to effectively make it one part. For example, this arrangement costs $47.10 plus $4.99 = $52.09. However, you get 8 of them so they end up being about $6.51 each ( a savings of $30.20). Of course, you have to snip the runners off when you get them (I connected them to the underside of the part so they wouldn’t show).
