To get back in practice with using and adapting Autodesk Inventor, I decided to design & 3D print a replacement Drop in Filter. This was as a retrofit replacement for my Minolta AF Reflex 500 lens.
My initial design replicated the locking mechanism of the original. Good for practicing Inventor’s simulation tools. However, on review, I thought KISS! Why try to replicate an intricate mechanism which ultimately failed in field use? So, I modelled a tether lug, with lock removed. 3D Printing (i.e. Additive Manufacture) was outsourced to i.materialise. Chosen process was MJF (Multi-Jet Fusion) in polyamide material. This is grey in natural finish, so I also requested the parts dyed black.
Fit tolerances for this task are sub-millimetre - So Inventor was the proven modelling tool in this type of situation. Everything fitted as designed, with screw in filters friction fitted to the holder.

Hello, would it be possible to purchase one of these drop in filter holders. I have the 500mm lens without any drop in filters. Thanks in advance, Andrew.
Hi, do you sell the drop in filter? I broke my filter and have tried using the filter from my 400mm lens, but want another solution. Thanks!
Thanks for your interest in this and taking the time to reply!
At the moment, I’m not intending to make it available for sale or free.
I would be concerned about being liable for any damage to the lens or lens filter during installation.
If released, the stipulation would be intended use as a dust cap only. Installation of any lens filter would be at own risk.
