Micromake C1 main belt tensioner by Lapinoo

Last crawled date: 3 years ago

This is a mod to add a tensioner knob for the main belt (X/Z) of a Micromake C1.
Parts are foreseen to be printed with the orientation as they appears on the Thingiviews. No support needed.
The following parts are needed:

For the knob assembly
1x Printed knob
1x M4x25 screw
2x M4 nuts
1x M4 washer


For the slider assembly
1x Printed slider
2x F623ZZ bearings
1x M3x25 screw
1x M3 nut
10x M3 washers (standard DIN125 washer, i.e dia 7mm, thickness 0.5mm)
Look on the pictures to see how the 10 washers are used. There are 2 groups of 3 washers on each extremity. These slide in a slot of the holder and help to guide the moving part. There is also a group of 2 washers on each side of the bearings (2 because the slider has been designed larger than needed to allow to put a GT2 idler instead, which is wider than the bearings).

For the holder assembly
4x M3x10 screws
4x M3 T-nuts
