Awesome help once again! Thank you so much!

Plastic pulleys on mine.

I tried to print another example in the makerware list.. the teapot... but it only did a few mm before coming off the bed and doing its flying trick...
So am I right in assuming that I need to upgrade the bed/sticking arrangement before printing anything else..*
Is there anything I could try immediately? I have 25mm blue tape but I'm not sure how to deal with edges of the many pieces or so it would take...* larger rolls seem to only go up to 50mm too.. so not sure..
I could head down B&Q now & pick up some of this if you think it'd help.. http://www.diy.com/departments/bq-ma.../246590_BQ.prd

Or would you try glue/hairspray on top of the red tape there already?*

Or will I buy replacement glass immediately?* An ebay one perhaps?* Something like this?* Although I'm unsure of what size.. need to think how much is possible to extend it by...

I have some calipers here and the cube I printed reads 19.90mm on both sides..*

Will try the circle once I work out how to make sure the printer won't be dislodged while printing...*
