In Colorado, you are not required to have side mirrors when you take the doors off a Jeep but please check the laws in your area to ensure this design meets the legal requirements for side mirrors.
When I take the doors off my 2022 Jeep wrangler (JL), I don't NEED a mirror but I feel a little stressed out when changing lanes without one. Commercial mirrors for $60 on Quadratec are a ripoff and look dumb. I designed this model to hold the $4 sticky back blind spot mirror from Walmart here and bolt to the door mount bushings of your Jeep when you take the doors off. In addition to the mirror, you'll also need a locknut, bolt and washers. I forget the bolt specs I used exactly but it's probably better anyway to measure your Jeep for the right mounting hardware. The hole in the model will accept up to 5/16" or 9mm diameter. I kept the back flat for embossing your club or Jeep's name using TinkerCAD or similar.
This model is for the left (driver side) mirror which I mount in the upper door bushing. Mirror/flip the model in your slicer to get a right hand version which I mount in the lower passenger door bushing on my Jeep.
My proof of concept design wasn't strong enough and broke off when someone hip checked it so this one has bomber support structure around the bolt hole and now can take a beating. You would think the wind would blow them around when driving but I've had them up to 75mph with no issues.
