I made this model in 2020 for my mom and figured I could upload it and join the contest.

Its very easy to assemble. The image says what screws you can use and all neds to be sandwiched together.
I've added a few fillets on top of some of the holes to make it easier to self tap the holes with machine screws.
You need to tighten the gear arms screws for the friction to be just as tight so you can resize it. Be careful when tightening so you dont strip the holes with the screws. Hand tighten screws.
Mine was printed in white PLA with normal settings, no support.
