Shendrones Goldberg

Tiny Whoop replacement frame meant for Taulman 645 or PCTPE. Try other filaments at your own risk. Pillar needed for top of frame to print cleanly. Print the main frame without supports.

Insert motors from below. Glue the two pieces together with this (if you use nylon):

Print the nuts in TPU. I don't use them but you can print a couple to hold down the FC if you choose.

Use the Betaflight version with standard prop rotation on Acrowhoop, Beebrain, Beecore, use the Inductrix version for, you guessed it, stock Inductrix board.
