Mendel Extruder Bracket and Quick Release Spool Holder

Designed for the early (legacy) Reprappro Mendel. If you built one of these then you probably have a lot of redundant 8mm nuts on the top bars, an extruder mounted inconveniently on the side and nowhere to keep your filament!
This provides a bracket to re-mount your extruder on the top bars and also provides a filament spool holder. Designed for 16cm diameter spools although a 20cm diameter spool will just fit. To release the spool just flex the support brackets apart.
