After buying some boxes to store my bits and pieces on various shelves. I came across some wheel attachments to mount a model car or van to a base plate on a display case. which I had forgotten I had purchased.

Every time I try and attach them to a wheel using double sided tape, or glue they wont remain in place. I asked a friend to print me some more but make the edges higher but that was another mistake. I had some blocks printed which do a better job. I did in the past drill a number of holes (8 in total in the plinth of the case but i did not like the finish.
So what has been your worst purchase to date.
