V1.0.5 - 27/01/25 - Added alternate design for Rear Standard Base. this piece combines A20 and A20 removing the rear standard movement of Shift however it provides singificant better rigidity, completely removing the need to print these parts in Carbon Fibre PLA. Thus by giving up Rear Shift you can get a perfectly rigid piece out of regular PLA.

V1.1.0 - 30/01/25 - This is quite a significant update. As with the vast majority of the previous updates, a lot of work has been put in to adjusting the design of the front and rear standard to allow printing in standard PLA instead of Aluminium or Carbon Fibre, but yet still offer full rigidity and no flex on the standards, especially when using wide lenses. With this update, the front and rear standard can now be printed in PLA with no issues with flexing. You will note the rear standard bracket is an all new design, which not only removes all flexing due to the only fixing point being the two thumbscrews, but it additionally makes the rear standard shift movement smoother and far more precise than ever. The rear standard has very high tolerances to remove any slop, as such I highly recomend you print with .08 layer heights, additionally the parts when first off the bed, may require 'burning in' sliding the two parts together back and forth several times until the action is smooth. This also necesitated a slight change to the Ground Glass Holder, as the glass has now been recessed a further 2mm to account for the removal of flex in the previous parts. Parts effected by this updated are A20-1 - Rear Standard Bracket, A21 - Rear Standard Base, A25 - Ground Glass Holder, A30 - Left Ground Glass Retainer, A31 - Right Ground Glass Retainer.

V1.1.1 - 06/2/25 - Small update to hole tolerences for M2 holes due to change in supplier hardware. Only needed if using hardware kit purchased after 01 Jan 225, Parts affected - A15 - Front Lensboard Mount, A20- 2 - Rear Standard Bracket, A20- 3 - Rear Standard Bracket, A22 - Rear Standard, A25 - Ground Glass Holder.

V1.1.2 - 20/02/25 - After many requests I have added the ability to make the bellows removable. With the addition of 24 Neodinium Magnets and two new frames that are glued into the bellows, you can now remove the bellows for transport, storage or to try out new bellows with ease. The frames mount in recesses in the existing from and rear standards thus ensuring a light tight seal, the magnets are incredibly strong so the chance of the bellows accidentally detaching is non existant. Parts Effected A22 - Rear Standard, A15 - Front Lensboard Mount, A47 Rear Bellows Bracket, A48 Front Bellows Bracket.
