Rigid-frame tender

Rigid-frame tender - Assembly manual

Needed parts or materials (suggested, you can use other matches parts)

• 31 pieces M2.2x6.5 screw (DIN7981),
• several short pieces of filament 1.75 mm,
• cyanoacrylate glue (not essential but may be needed to glue the wheels to the axles).

Optional parts

• the tender is prepared for assembly of a set of lights (2*white LED 5 mm), you can also use white LEDs as an imitation of reflectors (even if you do not intend to connect them to the battery).

3D printing

• We recommend using PLA filament, nozzle 0.4 mm and layer height 0.2 mm, but you can test other settings.
• All files are in print-ready positions, you don't have to rotate it on your slicer.
• The elements are easy to print and do not require the use of supports, brims or rafts (the only exception is the wheel axles, they should be printed vertically. We recommend using a small brim).
• Print all elements with 100% filling (the wagon runs better if it is a little heavier, the differences in time and filament consumption when printing with a small filling are not significant).

Assembling of parts

• The sizes of the wheels and axles should match, but if they are too loose, try to stick them with glue. You can also slightly chamfer the ends of the axle with a regular sharpener.
  If the axle is too thick, you can gently sand the hole in the wheel or you can very gently change the scale of the axle file when cutting in a slicer (change the scale of the element only for horizontal, the vertical scale should remain at 1:1). We have designed a special wheel and axle assembly tool, you can print it and use it to make your work easier.

Maintenance

The axles of locomotives and wagons are plastic, so after long-term use, the vehicles may experience greater resistance and may creak while driving. To extend the time of trouble-free operation, we recommend lightly lubricating the axle with Teflon grease.

Compatibility with older versions

• On June 26, 2022, the way couplers are mounted was changed to make trains work better on tracks. If you downloaded models before this date, you can print and install the new version of TAQ01-coupler-auto.stl and TAQ01C-coupler-cotter.stl in older wagons (included in the free locomotive model). You can also flip all couplers upside down in older wagons, but this is not recommended — trains will not take curves well on the tracks.
