Ski Vise

This ski vise approach was inspired by two existing 3D printed ski vise projects:

The existing vises didn't have an attachment point for holding the center of the skis down (the tiedown point), lacked some documentation (like screw details), and used fasteners/screws that I couldn't easily purchase nearby. I designed a version that I can either temporarily clamp onto a table or board using quick-clamps instead of a hand-crank screw. I have been putting a 2"x12"x8' board on two sawhorses, then I used IRWIN quick clamps to attach the vises to the board. This has worked out really well. I'll add a make with photos of the parts in use.

Ski Vise

This ski clamp system uses a common base design, which is either screwed into a surface or temporarily clamped in place using hand-clamps, like IRWIN quick clamps. Each base is attached to either a tiedown or a ski clamp with 2x 1" long screws. This is intended for using with 2 ski clamps (one at either end of the ski) and 1 tiedown in the middle of the ski, see any ski tuning/waxing demo video on youtube for reference.

I used a mix of US and metric screws (which are much finer pitch than is ideal) because I had these already lying around. This will be annoying for everyone else... sorry!

I have included lists of the printed parts and the non-printed parts below.

Suggested use is:
1x [BASE] + [TIEDOWN]
2x [BASE] + [SC]

I'm printing from PETG (black and Orange Prusa PETG) and TPU (NinjaTek NinjaFlex Midnight Black TPU Filament). You can choose different materials, I want to avoid PLA because I don't know how hot the iron will heat up the printed parts. The TPU is intended as a compliant material to be grippy and to avoid marring the skis.

Note the printing orientations are designed to avoid issues with overhangs. There will be a thin skin printed across some holes, this is an intentional sacrificial layer to improve print quality and avoid support material.

I have already plated the parts in PrusaSlicer. The TPU print was a bit complicated, and I needed to adjust the z-height lower than I usually use for PLA. I also loosened the tension on the extruder gears to where it barely closed onto the TPU. The filament stripped the first two times I tried to print the parts. When I finally printed the parts correctly, the TPU parts had a lot of stringing, but with some cleanup the parts all fit/work well together.

[BASE] Base:

[PETG] ClampBase.3mf

This is plated in PrusaSlicer as “1xClampBase.3mf”.
4x [B] 3/4" screws + 4x [D] nuts for base reinforcement.
2x [C] 1" screws for attaching accessory to each base.
3x [I] Anti-scratch pads are stuck onto the bottom of each clamp base (or whatever other non-scratch material you want to use). This could also be a double sided VHB tape, if you want to mount the clamps permanently. Alternately, the bases can be screwed down. I have ~1" long screws. The holes are 4.25mm diameter, with 3 holes on each side of the base using a 1/2" spacing.

[TIEDOWN] Tiedown point for ski bindings:
[PETG] AccessoryRopeCatch.3mf

This is plated in PrusaSlicer as “1xAccessoryRopeCatch.3mf”.
2x [D] nuts for attaching to each base.
This part is designed to allow a length of [J] 3 mm diamater paracord to be used to pull down on the skis/bindings, in the same way that a tent can be secured with line tensioners (guy line tighteners).

[SC] Ski clamp:

[PETG] AccessorySkiClamp.stl & AccessorySkiClampSlide.stl (separate 3mf files also included)
These two parts print-in place together. Plated in PrusaSlicer as “1xAccessorySkiClampSlide-mk3s.3mf” for printing in place.

4x1/2" screws + nuts for reinforcing clamps.
2 nuts for attaching to each base.

[TPU] AccessorySkiClampRubber1.3mf
[TPU] AccessorySkiClampRubber2.3mf
[TPU] AccessorySkiClampRubber3.3mf
[TPU] AccessorySkiClampRubber4.3mf
Four pieces, all need to be printed for each clamp. Rubber pieces 3 & 4 are identical. These are plated as “1xSkiClampRubberPieces.3mf”. I used NinjaTek NinjaFlex Midnight Black TPU Filament.

Non-printed parts:

US Machine Screws (round head, ~6.4mm diameter head, Phillips drive):

[A] #6-32 x 1/2"
[B] #6-32 x 3/4"
[C] #6-32 x 1"
[D] #6-32 hex nut

Metric screws:

M3 Screws:
[F] https://www.mcmaster.com/91200A120/

M3 heat set insert:
[G] https://www.mcmaster.com/94180A331/

M3 Knurled Knob (< 10 mm diameter head):
[H] https://www.mcmaster.com/91175A061/

Self-stick felt anti-scratch pads (for furniture legs)
[I] 1" to 1-5/8" felt pads, these can be up to ~42 mm diameter.

Paracord:
[J] 3-4 mm paracord when uncompressed, 2-2.5 mm when compressed between calipers. I have yellow "550 Paracord Parachute Cord Lanyard Mil Spec Type III 7 Strand Core"
