Nikon Lenses Stand

This is stand has three parts. Base (the main one), Lock (the spring button to lock the lenses onto base) and Cap (threaded cap to protect down base. If you want just a stand to put lenses over a desk, lock and cap are optional. The base has eight side holes to “stack” more than one unit. You may row some stands to keep some lenses inside a bag e.g.
 

The base has a small hole (2 mm) which is the index to align the lenses to mount (the “black point” on lenses).

The lock bar, must be super-glued to base. There is a rectangular hole under the base to attach the bar. One glue drop is enough to attach.

The cap is threaded to attach to base and may be removed for cleaning.

I've used PLA, 0.2 mm / layer, 2 layers top and bottom, 30% infill.
