RF100 Filament Holder Extension for Kaisertech filament

Some filament spools are too broad to fit onto the spool holder coming with the Renkforce RF100, e.g., the Kaisertech spools sold by eBay seller holi-europe. This part extends the Renkforce RF100 spool holder so that these spools fit. Print with low quality, 25% infill and a skirt.
