About this 3D model

Alright, this one likely wont be very popular, but if i upload it here i might actually be able to find it next time i need it, lol, this is organized a little better than my personal filesystem. Anyway i made these for my 1998 jeep grand cherokee (i dont know the fitment for other vehicles, you'll have to figure that out yourself), it has a mechanical fan and has troubles staying warm in the deep freeze of Canada's winters (which prevents you from getting much heat in the cabin), most people just use cardboard zip tied to the grille to restrict airflow, but i figured this would be less obvious and less ugly… Fits nicely inside the grille holes, and there are 7 holes total so you can use however many you want for your desired result, i intend to use 5 because i have LED pods in 2 of the holes so i didnt want to design a whole different piece for those 2… easily removed by releasing the top latch most can be release with your finger, some spots may be too tight and you can use a screwdriver or something.. I just printed in PLA+ i figured these will be removed in warmer weather anyway so they shouldnt need to be ASA, but they may get heat coming off the engine causing them to fail but i only intend to use them in exteme cold so i dont think that will be a problem… time will tell, i may re-print them in ASA if i find there's a need. (i did forget to take them off when i parked the jeep for the summer and of course the heat did mess them up, so i re=printed in petg this time. they're small and easy enough it's not a big deal to re-print em anyway) . . Just a follow up, took the ol' jeep for a rip today, the block offs worked well, it quickly got up to 190* (thermostat temperature) and stayed there the whole time, got some good heat and much faster then previously.
