hello,
i got a 3d printer a few weeks back and wanted to share some designs i've made for my 92 240.
you can see here for a better cupholder design that i've created (

i found that the existing models restrict access to the stereo as the cups are always in the way. and are also just not a visually appealing solution, in my opinion, so i figured the center would be the best location for this. newer vehicles feature rubber feet that surround cupholders so that more cup sizes can be used and still be stable. i intend on implementing this in the coming weeks if needed, and just putting in a set of them i can find on ebay or something.
i also created a double din stereo fascia to adapt a Sony XAV-AX-210, a carplay/android auto stereo equipped with a CD player, so that i could have this in the volvo as well.
i referred to a posting in ozvolvo here (
https://ozvolvo.org/d/16609-16609) to build upon and print, but didn't really like what the model did to the heater vents as, to be honest, i didn't really want to go through with re-routing them with pvc tubing and didn't think they looked as good as stock. this also eliminates the possibility of installing gauge pods there, or a phone holder, etc. i considered the fact that i didn't want to block airflow while the heater is on, so holes follow along the length of the blower vent so that the heater isn't inhibited. mounting tabs are attached to the side of the stereo plate to attach it to the vehicle which can be found via the ozvolvo link in the file posted there.
let me know if you have any questions. i'm not a professional 3d designer or anything, but i figured these could help others get a starting place for their own projects - just as the above linked forum post assisted me greatly.
