Summary

Just added some mouse ears to the fins to help prevent warping on this difficult raftless print.

Instructions

You're going to need almost the entire print area of a ToM - so countersunk bolts would be really handy or else the nozzle might collide with your bolt heads.

Just print it and then snap/cut off the thin disks.

Just wondering, is this the 18 or 24 mm motor version?

Mouse ears seem to be working. Probably flies just fine with them on, too :)

Yeah, completely eliminated the warping for me. They cut off easily with snips or if you're really careful you can bend them till they snap off. Only remaining problem is I still got a few cracks forming in the wings. I wonder if a vertical ridge near the end of the fins would help prevent the cracks without effecting flight?

The can come very handy for not so fine tuned printers too. I used them in

, and yes, just make it one layer thick and then they are very easy to remove or you may just keep them.

Tried printing the eared version today. Warped about the same for me, but I'm using an oddball build surface.

This seems small enough that if that perimeter line was omitted there wouldn't be an issue...

Yeah without the outline, you should be good.
