Not sure if this is OK, my first non hello thread, but I recently did some custom printed ultralight guy string winders to my design with all the fat taken out.
In the UK SOTAbeams sell a lot of well thought out portable stuff but my friend was keen to do me one so we evolved a design he downloaded. Our design is similar to one of the SOTAbeams one in size but 1/3rd the weight and possibly more capacity.
