What is this!?:
This is a mount for an off the shelf rotisserie. It's used when applying epoxy to an item to help with even dispersion. With something like a tumbler(cup), you can let it rotate while you apply epoxy and it keeps the epoxy from pooling in any one spot. This can also be used with some 3D prints for print smoothing. If you have a semi symmetrical design you can mount it to the end of the rotisserie and apply epoxy. Once it's applied just leave the rotisserie on until the epoxy is cured and you should have an evenly covered 3D print!
Before designing this my rotisserie was stacked on two reems of paper and had some putty on the bottom to hold it in place. Needless to say, I needed something a bit more...professional. With that said I present the Tumbler Turner! It was designed around the 'Char-Broil' brand rotisserie from Lowes but that same exact rotisserie model seems to be sold under quite a few different names by different sellers (Home Depot, Amazon, Walmart etc).
There are a few variations of the model to fit different needs.
Full: The two files RMountFull and RMountFullScrewHoles are the entire model merged into a single piece. If you have a larger print bed and don't want the ability to use the dowels to extend the space between the rotisserie and the end support. Self-explanatory the RMountFullScrewHoles has screw holes for mounting. Fits a standard #6 wood/drywall screw.
Without screw mounting holes: Rmount and Stand are what is pictured in the above images. They do not have screw holes for mounting. You can still use command strips or other means to secure the rotisserie mount.
With screw mounting holes: RMountScrewHoles and RStandScrewHoles have chamfered holes for standard #6 drywall/wood screws. This should allow a VERY secure mount to whatever surface you'd like.
All models use the same updated-clamp so print one of those with any design choice.
To assemble you'll need to take off the front metal plate secured by three silver Philips screws. Once that is removed the rotisserie will slot into the 3D printed model and the same screws can be used to secure it in place. While screwing in the rotisserie be careful to align the square hole as my rotisserie had a good amount of play and needed to be guided into place.
If you printed the stand and the mount in two pieces, you'll now need to use a wooden dowel to attach the two pieces. You'll need two 120mm lengths of 9mm wooden dowel to attach these. They can be bought at any local craft or hardware store and most times even cut with an xacto knife. If you want to make the turner longer simply cut your dowels longer and insert them, it'll space the rotisserie and the end mount farther apart. The dowel should be a good pressure fit but if you'd like you can add some hot glue.
If you printed the full mount in one piece you're ready to insert your metal rod.
I cut the rod down to a desirable length for the tumblers that I typically do so test fit some of your tumblers to get an idea of how much you want/need to cut off of yours. If you left some length on your dowels you may not need to cut this at all.
The clamp is the last piece that you'll want to attach, after you've cut the rotisserie rod. First we will want to add the nuts and screws to the updated clamp model. The model is built for use with two m3 nuts and screws. The screws should be m3 x 11mm - m3 x 12mm, longer will work but will protrude from the model. After slotting in the nuts, insert the screws and thread them so they are started but not protruding into the area the rod needs to fit(test fit the rod if needed to be sure). Moving back to assembly - Insert the rod through the front hole in the model, about half way and then slide on the updated-clamp with the long portion facing the front of the turner(away from the motor). Slide the rod all the way back into the motor housing and slide the clamp forward so that the round/long portion of the clamp model slots through the front hole(see assembled picture with copper/gold colored updated clamp). This will help with a smoother rotation as well as ensures that the rod does not vibrate out of the rotisserie. Secure by tightening your two m3 screws.
