Parametric Hummingbird Feeder Heater

I printed https://www.printables.com/model/330704-hummingbird-feeder-heater-remix-rubber-band-attach but discovered that it was both too small for my feeders and the bulbs that I bought. So I designed my own parametric version.

You will need a “replacement cord/bulb for salt lamp” which are easily found for sale online, and want a bulb around 15W. The kit that I purchased came with 25W bulbs so I use the dimmer to keep them at half power.

I've included some models for my larger feeders (118mm diameter, 29mm hole for bulbs), and some that are closer to the other sizes (110mm diameter, 25mm hole for bulbs). I also included a larger 140mm version with slots to fit a style of feeder where the perch is attached separately and interferes with fit.

If you need another size or configuration, please leave a comment with measurements and I will happily add it. If you're comfortable with CAD, you can also just use the parametric source at Onshape.
