Print on flat surfaces, spikes/details facing up [or down for resin?] print a peg for each hole 7(?) I'm currently in the printing phase plan to glue model together and prime/paint this sucker at a massive 220% scale, which in the original by adonfff [model src] I'd say knock a percentile or 2 off the peg, I printed mine 219% and it's very snug/snap fit, might be ideal for lack of glue.
The author remixed this model.
