RileyLink case Omnipod version

This is my design for a case to replace the original supplied with the Omnipod version of the Rileylink. I designed this for somebody who lives reasonably close to me who's Rileylink case had broken but as the Rileylink itself was in use - it controls an insulin pump - I was not able to spend much time with it and get to grips with what space is available internally for fitting a securing mechanism - nuts and screws.

My case design, which encloses the Rileylink plus battery, keeps the two halves of the case together using two pairs of neodymium magnets and a friction fit. There is a "string hole" in the top half should it be required to attach the case to a lanyard or something similar but note that I have not personally been able to test this design and although the feedback given below is encouraging, anybody who uses it must do so at their own risk.

I have tried to keep the case as small as I could whilst maintaining enough internal space to accommodate the electronics. There are two versions of the bottom part of the case, the "LS" version has a hole for the on/off switch which is a wee bit larger than the original.

To date, I have made and distributed four of these, each printed on my home-built Mendel90 3D printer using a translucent ABS material. Feedback has been good, "My son only changed RL over a few hours ago but so far he’s very impressed. Says charging port very easy to access and stays in well. Likes the magnets and says feels secure. He also likes the base being more translucent so easy to see the green light."

For the "LS" version: "Much easier to reach the slider too!" and for the other bottom half: "The on/off switch position is fine. It’s a little tricky to use (need a paper clip or similar)."

I have not sold any of these for profit and hope that in the spirit of the Open Artificial Pancreas System project my files will be used in the same way - for personal use, to help others and not made for profit.

Notes:

Support only needed for the top half NOT required at all for the bottom

Remove the support material from the top half and clean out the space where the antenna fits. A 3mm drill bit is useful to remove any support material in the gaps left for the magnets.

You will need four neodymium magnets, 3mm diameter and 1.5mm thickness. These are a push fit into the gaps and secured using some form of "Superglue" - take care!

Make sure that you also take care to align the magnetic poles appropriately - it may be obvious to state that the magnets in the top should attract the magnets in the bottom part but it is really easy to mess things up - check and check again :-)
