For Halloween I designed a set of modifications to turn a pumpkin, into a light up turret from the popular game series, Portal.

You can watch a video of me making it on my channel here:

This set is designed to fit a pumpkin between these sizes:
Min: W10cm/D10cm/H15cm
Max: W18cm/D15cm/H20cm
If you'd like to use this with a differently sized pumpkin, just re-size the parts accordingly.

I've included below all the files in STLs, as well as in bundles both as 3mf project files, and gCode ready to put straight onto a Prusa Mk3s using PLA.

In the 3MF I've set up modifiers to ensure strength is focused in the areas which matter, but if you are using the STLs yourself, I'd suggest ensuring any weight bearing parts are 30-40% infill and the rest can be 15% infill.
Make sure the lens part is printed at 0.1mm layer height or smaller.

The LED holder is designed to take 8x 5mm LEDs, which I've powered using a standard 2x AA holder with power switch.

I hope you enjoy printing and using my design. To help me keep designing and uploading more things, you can tip me via 'Buy Me a Coffee' here: https://www.buymeacoffee.com/JoshForwood
