The original “Tape to User Port Adapter” model didn't allow you to use the Tape Port in conjunction with the User Port. This model resolves that issue by raising the Adapter above the tape port. It uses a special lock piece that fits inside the tape port to hold te Enclosure assembly in place.
If you never use the Tap Port, I recommend using the original version which you can find here: https://www.printables.com/model/749549-ultimate-64-tape-to-user-port-adapter
Print Settings:
Layer height:0.2 mm Perimeters: 3 Infill: 15% Support: Only some support on the front of the Userport base is needed to prevent sagging. (I used ‘paint on support’ + organic support). The ‘ComboStand’ can be printed without support.
Additional hardware required:
None. Everything just snaps together.
Assembly Instructions:
Insert Userport Adapter and press down. Make sure it's flush with the bottom.
Guide the ribbon cable through the Tape connector opening. (Make sure that the Tab on the connector aligns with the opening on the Userport connector) Insert the connector
Insert the ‘Lock’ piece into the C64 case. It should snap in place, but you may need to bent the outer wall of your case a little bit to get in place.
Add the legs to the case. You can sand or file the tabs a little bit to make the surface a bit smoother. Because the tolerances are quite tight and the tabs can otherwise break off if you try to remove the legs from the base enclosure. Tip: Wedge a screwdriver between te leg part and base to help gently separate them.
Attach the top cover. Make sure it is aligned correctly on all sides before applying force to press it down. (Be careful to not break the legs)
Pull everything towards the case. The leg piece should latch onto the lock piece.
