FD to EOS RF extension tube.  Using a 50mm as a macro is the only practical use of an FD lens.  Experiments showed the minimum focus distance becomes 80cm if the FD is 15mm beyond the EF flange distance.  Unfortunately, the FD becomes fixed focus because this makes its maximum focus distance the same as its minimum focus distance.  The 50mm is visually too similar to the 100mm to justify this idea.

Pop socket.  These have faded from popularity, but lions wanted to use them as handles for other gadgets.  The trick is getting them to stay closed or stay open.

  • Rectangular bed extension

    The idea came of extending the bed in the Y direction to 400mm.  It would require a longer track, longer belt, & longer hot plate in the Y direction only.  It would allow the lion kingdom's largest panels to be printed in 1 piece.  

    A rectangular expansion requires far less new parts, takes far less space & would be far more used than a square expansion, yet only square expansions are made.  The cheapest 400mm one costs as much as a new printer.

    It could be ground down to 400x235 to fit in an apartment, but that would throw away all the other parts required for the 400x400 upgrade.  The next idea is just finding a longer track, longer belt, & longer hot plate.  Ideally, the hot plate would be divided so the entire thing didn't have to be heated for every print.

    The lion kingdom has always believed the inventor of the pop socket has gotten over compensated through a very effective patent enforcement program.  By now, there's no reason such a simple thing should still be even $10 in fiat money.

    Lacking a desire to spend $10 to reverse engineer such a thing, there was finally a good profile shot of the mechanism.  It's basically 2 toilet plungers stacked.  A system of 2 curved profiles & 2 square profiles make the toilet plungers.  The curved parts bend & lock into an inside out & inside in position.  The square parts create a vertical offset required by the curved parts to lock into the inside out position & divide the height of the retracted position.

    The trick is TPU delaminates if bent across the laminations.  Something would have to be done to strengthen the laminations or it would have to be printed as a flower.  The only reason it locks into 2 positions is the tension propagated around the circle.  It wouldn't work with separate flower pedals.

  • Unheated bed

    The answer is yes.  You can print without heating the bed, if the apartment is already 93F & you have a grip bed.  It doesn't stick as well, but it costs less & it doesn't make the apartment hotter than it already is.
