Multiformat Development Spool Jobo2830

Multiformat development spool for the Jobo 2830 tank.
Supports:
4x5, 4x10, 5x7, 13x18, Wholeplate, 18x24 and 8x10 sheet film.

Edit 24 Jan:
- Added 4x5_Seperation.stl, this allows for 2 4x5 sheets in each grove. Use the 5x7 setting and load the 4x5 sheets with the 5" side.

Use a PVC tube with 32mm outer diameter as center column. Secure the PVC tube to the bottom part with two M3 screws & nuts. Slide on the drilltemplate and mark out the positions for the needed holes in the center column. Drill 3.5mm holes on the marked locations. Instert M3 screws and nuts in the top part, M3 knob optional and just sett the negative height by screwing the M3 screws into the appropriate holes.

The 8x10 (and likely 18x24) sheets are a bit wobbly, likely due to its size, thus use with care. Or just use the 2830 as normal with two 8x10 sheets and no spool.

The clamps to secure the film in the tank are a first approximation, feedback would be much appreciated.
