corrective lense TPU frame for cycling glasses

This is a holder frame for corrective lenses/spectacle lenses. The frame can be attached to cycling glasses. The holder frame must be printed from TPU, preferably TPU 95A. To obtain a usable print, the TPU must be dried and the settings from the print profile must be used. These are slow print settings, but they result in an optimal print.

If the frame is too large or too small for the lenses, the size can be adjusted in the slicer. The holder consists of three parts in one assembly. Adjust the size/thickness of the individual parts and move them to a suitable position.

Inserting the lenses into the frame requires a little strength and skill. The frame must hold the lenses securely in place, otherwise they will fall out if subjected to vibrations. The position of the lenses in the frame is important for good vision. You will need to experiment to find the optimal height for you. After 2-3 attempts, I managed to insert the varifocal lenses in the correct position.
 

Background:

Some cycling glasses are supplied with an additional frame in which corrective lenses/spectacle lenses from an optician can be inserted. I have designed a replacement frame made of TPU material that fits all spectacle lenses, so that any non-customised spectacle lenses can be used. For example, I took the spectacle lenses from an old but suitable pair of glasses.
