 Now the problem is that I don't know how to modify the thickness of the rubber band. 

Do I need to make additional parts?

For the round band template ldcRubberBandRndSeg.dat is used. You could copy that to e.g. ldcRubberBandDuploRndSegDup.dat and then edit it to scale it up. (e.g. replace all 2 values with 4 to make it twice as big).

Then you need to also make a new template, for this you could copy the normal one 'rubberBandRound.ldr' to e.g. 'rubberBandDuploRound.ldr' and edit it to use the new donor (replace 'donPart=ldcRubberBandRndSeg.dat' with 'donPart=ldcRubberBandDuploRndSeg.dat'. Optionally also change the template description to '0 Rubber Band (duplo, round)'

It's best to do all this editing while LDcad is closed, then when you reopen it there should be a new band in the templates bin.
