Pinned straw:
A comprehensive review of 3DP at this point in time @Bradbury and I note that you have included a bunch of their previous announcements (at the end) that they have failed to follow up on, i.e. collabs or new opps that never panned out into anything of substance so were not mentioned again.
I think you're correct to weight your Val 60% to your bear case to give a valuation that is even lower than their low share price yesterday, considering that their history is of sub-par management that overpromises and underdelivers and a company that lurches from one tiny capital raise to another just to keep the lights on.
There would be few members here who still hold 3DP IRL, and of the 27 members who still have 3DP on their Strawman.com scorecard, only 14 of those 27 (roughly half) have a positive scorecard (portfolio) return for their entire Strawman journey, suggesting some of the others may not be very active members or may not be actively managing their Strawman portfolios (scorecards).
3DP demonstrates NONE of the attributes that I look for in my investee companies, so they remain well off my radar, but it is interesting to see that some people still think they're going to come good, after all of this time, and all of these disapppointments that they have delivered.
On the other hand it's refreshing to see, @Bradbury that you are more realistic, and are factoring in past management behaviour and track record, resulting in the bull case being discounted as a probable eventuality, i.e. it could happen, but the bear case is more likely based on prior history.
All in all, a good summary of 3DP, the range of possible outcomes, and a well reasoned valuation that is lower than where the company last traded. I like it!
