Ligero69 mods

LIGERO69 plus.
It's based on REV.E original Ligero, left untouched but some small changes were done to simplify building for those who do not like nuts-in-slots assembly
upper lip is fixed with 3X SELF TAPPING 2MM flat-head screws.
Lower lock is held by 2X M3 HEAT INSERTS used ones are 6 or 8 mm long
Only the lens lock was left on an M2 nut because seems the best and most reliable solution. One small drop of glue will leave you with the perfect result.
The light-sealing inner lip was tapered 0.3mm to better fit the old Mamiya focusing screen box and old backs (type 1). I printed PLA, 3 walls, 25% infill cubic subdivision or gyroid.

I printed lips and back lock lock in PETG or PCTG. 3 walls 50%infill.
M2 and M3 thumbscrews rely on cylinder head hex screws or other screws you may already have around. I put one washer between the M3 thumbscrews and the lock.
Print the thumbscrews with the larger hole up, no supports.

I made a side sliding lock, graflock style, with and without thumbrest, and printed thumbscrews for the Ligiero69 camera. Hope others find it useful.
