This is a quick model to provide a handle for a comb which can be used to quickly sift out debris from your 3d printer's resin vat. Here it is used on a Wanhao D7 Vat but the idea should work for any similar vats.
The dimensions for this handle where it snaps onto the comb is a slight taper starting off at 3.5mm and then tapering down to 3.0mm. Depending on the comb you have, you may need to scale this up or down slightly and/or apply superglue for a more secure fit.
