The author remixed this model.
Original Model:

I was not a huge fan of the eye, so I modeled one to look more like the turrets from the game. The print file is set up for two filaments. Start with clear then change to black for best results.
Click the link above for the original model. My remix is only for the eye piece, so you'll need to download the rest of the model from the link above. The eye piece is 2" in diameter. you'll need to scale the eyepiece down if you use the original model files at scale. I scaled the model files up 120% to fit my pumpkin better. The eye was made to fit with the other pieces scaled up to 120%.
If you want to make my exact pumpkin turret, I scaled every piece up 120% (NOT THE EYE) and carved the 13" pumpkin from Target. I used hot glue to hold the side pieces and eye piece on to the turret. https://www.target.com/p/13-34-carvable-faux-halloween-pumpkin-orange-hyde-38-eek-boutique-8482/-/A-84064494?ref=tgt_adv_xsp&AFID=bing&fndsrc=tgtao&DFA=71700000035367417&CPNG=PLA_Seasonal%2BShopping_Brand%7CSeasonal_Ecomm_Home&adgroup=SC_Seasonal_Halloween+Decor&LID=700000001230728pgs&LNM=PRODUCT_GROUP&network=o&device=c&location=&targetid=pla-4584551178560596&gclid=e14ca541bcac1bf95026c05b904e765d&gclsrc=3p.ds&ds_rl=1246978&ds_rl=1247068&msclkid=e14ca541bcac1bf95026c05b904e765d
