I sent two versions off to be printed: the one above and the one below where I added a screw post to match the threads on an arrow shaft insert. Shapeways changed there interface a bit but it only gave me one plastic option to print with. I’m guessing it had to do with the fine details on the threads. Each model cost me $5 to print. With shipping and tax it came out to about $15 to print them up. We’ll see how they look.
I opened up the dimensions a bit on the shaft to allow a bit of slop for the threads to catch. This thing is so small I am not sure I opened them up enough. I guess I will see when it shows up.
I am slowly creeping along on this project. Here is the new 3-d printed part with arrow shaft:
The arrow shaft screws in tightly to the plastic frame. I could probably open up the dimensions a bit more. I think some of the tightness is residual from the sintering process:
The frame without the threaded shaft has some slop between the shaft and the hole (no picture). I think it would work fine glued but I could tighten up those dimensions.
I got the arrow shaft from a local archery range. He gave them to me with a handshake and a promise mention them to any friends looking for an archery range/lessons. He was a real nice guy, check him out if you are in the neighborhood looking for archery lessons or a range: http://www.southbayarcherylessons.com/
I snipped and clipped and folded the bag into position:
and found I have about an inch too much bag for the frame :(
I didn’t expect to be dead-on but I am a bit embarrassed how far off I am. I guess measure 18 times and 3-d print a dozen times… as the old saying goes. I am probably going to just fold it over and make do with the way it is to see how it works out.
