Everything is dialed in now in Slicer for my good old MakerBot Thing-O-Matic.  I recently started printing with PLA instead of ABS and I can honestly say I am getting used to it.  ABS certainly has it’s place but PLA does print really nice too once it’s dialed in.  I made this fantastic Valentines Keychain for my family members.  This was printed called to 75% of the original size from the original Thing posted on Thingiverse.  This cool print in place one piece design with moving centerpiece is well done.  You can download it here:  Valentine’s Day keychain
