About this model

This is a remix to our previous design: Flexi-rex with hole for keychain The main reason we made this remix is because we received a number of feedback regarding to the loop (in our previous design) felt off easily during/after print, hope this design can fix the problem. =) No supports is needed *else the keychain loop might filled with supports, hard to remove" Printed with brim Tried scaled and printed with 80% size, the keychain can hardly fit in, 85% is just nice if you are thinking of printing a smaller one. Have fun printing! =) *Feel free to follow our Instagram: imaginacians
