Eloflex battery plug

Battery cap for Eloflex wheelchairs. They generally come with one cap, but when you travel by plane, a second one would be good, as you're supposed to cover terminals with electrical tape. This friction fits so much so, I can't get it off without a screwdriver. I made both a PETG and PLA version. I think PETG is better suited for this, unless you just put it in and never take it off. I recommend putting this cap on the plug you don't use to attach to the wheelchair and keep the original cap for using on the plug where you take off the cable.
