SpaceX Starship bird feeder

As the winter approaches, it's time to put out some feeders for our feathered friends.

Since my previous feeder model was vaguely rocket-shaped, I decided to design this one to actually look like a rocket, specifically, the SpaceX Starship. 

The feeder consists of 3 parts:

1. The main body
2. A base insert for the bottom
3. A securing pin 

The base insert is tapered and has an SpaceX X logo-shaped hole to allow for any rainwater to drain. The pin goes through the main body and the base insert to hold it in place. 

There are 2 versions:

Normal version

The normal version has a main body just under 202mm tall which will print on Prusa MK4, MK3 and similarly sized printers. It the whole thing prints in less than 4 hours on my MK4.

XL Version

The XL version has a main body that is 330mm tall, designed to print on the Prusa XL. It's pretty big but maybe the birds will be extra hungry this year! It takes about 9.5 hours to print the XL version on my Original Prusa XL.

Printing guidelines

Orientation

The main body prints standing up. I turn on brim since it is relatively tall compared to the thin contact surface on the bed.

Print the base insert flat side down.

Print the pin on its side, with the chamfered part of the hole facing upwards.

Material

I printed mine in Prusament Galaxy Silver PLA, using the 0.2mm STRUCTURAL profile. I've printed similar bird feeders in PETG in the past, so that should be good too (and perhaps even better given that PETG is less brittle than PLA). 

Supports

The only supports required are to support the upper 2 flaps of the main body. I use organic supports. In PrusaSlicer, set supports to “For support enforcers only” and then use the paint-on-supports option, smart fill mode and paint the bottom of the 2 upper flaps.

Assembly

Insert the base insert to the main body, aligning the holes on the insert with the holes on the body. There are locators on either side of the base insert to align with the lower flaps.

The locking pin goes through aligned holes in the main body and the base insert. The handle end of the locking pin is tapered to the curve of the main body.

The holes are sized to be small enough for the peanuts to not fall out but big enough for the birds to be able to get them out. That results in the 2 models being different in their alignment of the holes.

Normal version

On the bottom row, there will be a full hole on the middle of one side and a vertical bar on the other side (i.e. holes left and right of center). Ensure that you match this on the insert and the main body. Due to the alignment of the holes, the pin goes through at an angle in the normal version.

Insert the pin from the left of center to the center hole on the opposite side. See images below.

XL version

The holes on the bottom row are symmetrical about the flaps, so it's simpler. The pin goes straight through the hole to the left of center to the hole to the same side of center on the other side.

Don't forget to upload your makes and hit the ❤ on the model if you like it.
