I have a RepRap that I built as part of the Round 1 TVRRUG. Printer was fully completed and working perfectly (at least the last time that I powered it up, a couple of years ago). From memory the endstop microswitches weren’t very effective, but I think that was a feature rather than a bug. I also have several reels of filament, which, given the age, would probably need drying out.
From reading the forum I suspect you already have all the 3D printers that you want at the space, but if you think it could be useful then please let me know, happy for the makerspace to have it, or if you have any suggestions of worthwhile causes, please let me know.
I could probably deliver to the space, or collection from Merrow in Guildford.
