Being machine tool mechanic I appreciated the complexity and precision of the
gearbox and rubber motor
Good job! Will try something else
“Butterfly” mechanical model kit
I love it.
I love this model - it was so much fun to build and I’d recommend the project to any UGears fans.
I ordered the bitterly and was sent the timer, with no return slip. NOT only, did they refund my money the let me keep the puzzle. I thought that was pretty great service. Will definitely give them my business again!
