Thumbs up Fixed the Arm Cuff on My Deleon With a Little Help From a 3D Printer

I use the clean sweep coil on my Deleon whenever I do dry sand hunts at the beach and it’s a heavy coil. I believe that this weight adds a lot of extra stress on the arm cuff and well I guess this last Sunday it finally took its toll when the arm cuff cracked down its length. (Pic 1) Since the arm cuff is built into the battery compartment I couldn’t just build a standalone arm cuff and reattach it. So I thought I could do something with bracing. I decided to make a pattern so I traced the good side and cut out the pattern. (Pics 2 & 3) Now that I have the pattern I had 2 choices. One, I could cut pieces of plastic using a scroll saw or give the pattern to a friend that has a 3D printer and let him make them for me. I chose the latter. (Pic 4). When I got the braces from him I was surprised at their strength and lightness. However, when I got home I found that they weren't as perfect as I expected it to be so I took my Dremel and sanded down a bit and shaped each piece to fit as best as possible. I then cleaned the pieces and the surfaces it was to be epoxied with alcohol. First, I put a nice long bead of epoxy on the cracked piece and then I put in 3 braces (Pic 5 & 6). As a prophylactic, I did the other side as well (Pic 7). I then mixed up some epoxy and filled in any gaps between the braces and the arm cuff. It seems to be incredibly strong and I do not expect to have any future issues.

That's a great idea...I work at a polytechnic institute, many 3D printer's around...will probably do something similar if I ever have another cuff issue...thanks for sharing!

Should do it...

I fixed a friend's similar arm cuff. I removed the padding, and epoxied a half round PVC piece made to fit, inside all the original...

Yours looks like it could build up with ice though...

I have seen a lot of parts and gizmos being made for detectors out of 3D printers.

Only if I put it in the freezer!

That's a great fix!

3-D printing is going to make for some
amazing changes in manufacturing and repairs

That looks really good. I need to do something like that for my battery pack leg/stand.
