toneCarrier 35 mm and 120 assembly guide
Step 1 Insert M5 nuts into the housing
-
1
Lay the A-side of the housing flat on the table
-
2
Take 6x M5 thin square nuts (DIN962) and insert them into the slots around the bearing pockets
-
Depending on print quality the nuts may be slightly loose on their pockets. Keep the assembly horizontal to prevent them from falling out.
Step 2 Insert bearings
-
1
Take 4x bearings (type 688) and insert them into the pockets in the housing
-
2
Put the housing to the side while working on the next step
Step 3 Roller screws
-
1
Prepare 4x M3 thin square nuts (DIN562)
-
2
Insert the nuts into pockets in each of the two long rollers
-
3
Use a thin tool to push the square nut all the way into the pocket
-
4
Insert a M3x40 socket head cap screw into the roller as shown and lightly tighten with your fingers
Step 4 Roller O-rings
-
1
Take 8x 15x19x2 mm red silicone O-rings
-
2
Place the O-rings inside the grooved at both sides of each roller
-
Wash your hands before handling the O-rings to prevent them becoming dirty and contaminating the film
Step 5 Continue housing assembly
-
1
Place the rollers in the housing assembly from step 2 as shown
-
2
Check the orientation of the top (long) rollers. The M3 screw must be pointing up.
-
3
Take 2x top spacers and 2x bottom spacers and place them over the locating pins in the housing as shown
-
4
Place the remaining 4x bearings onto the roller shafts
Step 6 Put the housing together
-
1
Lower the B-side of the housing onto the rollers
-
2
Gently lift the entire assembly while keeping it horizontal and press the housing together
-
This step should not require much force - if you struggle, stop and confirm that all parts are placed correctly to prevent damage.
Step 7 Close the housing
-
1
Take 4x M5x45 socket head cap screws and insert them into the corresponding holes in the corners of the housing.
-
2
Tighten the screws using a 4 mm Hex (Allen) key in an X pattern (top left, bottom right, bottom left, top right)
-
Do not tighten the screws excessively to prevent warping the housing.
Step 8 Install the pulleys and belt
-
1
Turn the housing around and slide a 20-tooth GT2 pulley over one of the rollers
-
2
Tighten the pulley using a M3x2.5 mm hex (Allen) key
-
3
Install the timing belt by placing it over the pulley and lightly stretching it over to the second roller shaft as shown
-
4
Tighten the second pulley
-
Leave a small gap between the pulleys and the housing to prevent unnecessary friction
Step 9 Install the belt cover
-
1
Place the belt cover over the belt and pulleys as shown
-
2
Secure the cover with 2x M5x25 socket head cap screws and a 4 mm hex (Allen) key
-
Do not over-tighten the belt cover screws
Step 10 Install the knobs
-
1
Lay the assembly flat with the remaining roller shafts pointing up
-
2
Carefully remove the previously inserted M3x40 socket head cap screws
-
3
Install the 2x knobs into the shafts and secure them using the M3x40 screws
-
Tighten the screws firmly, as they are structural and essential for preventing the shafts from breaking during use
-
Do not turn the shafts while the screws are removed as it may cause their retaining nut to fall out
Step 11 Install the feet
-
1
Attach 4x feet to the bottom of the housing using the self-tapping M3x8 screw and a 2.5 mm hex (Allen) key
-
2
The screws are cutting a thread in the plastic as they are turned. This can be quite difficult - an electric screwdriver on low torque setting can help!
-
3
Attach 4x self-adhesive rubber stickers into the corresponding pockets on the feet
-
Do not overtighten the screws as you may strip the plastic and have to re-print the part
Step 12 All done!
